Tetra Pond Sticks Have a New Recipe. Do Pond Fish Still Eat Them?

Tetra's own listing admits the pond sticks recipe has changed. Most of the 100 most recent UK buyers never noticed, five did, and most of those five say their fish stopped eating. How to tell which camp your pond will fall into.
Tetra's own listing photo says it: "Less is more", an old green tub next to a new dark one, a paler stick in the magnified circle, and a footnote that during the transition period you may still receive either product. So the recipe change that five of the 100 most recent UK reviewers complain about is not a rumour. It is printed on the listing.
That makes this a slightly different review from the usual pond food write-up. The headline numbers are still very good: 86 of the 100 most recent reviews are five stars, the recent average works out at 4.59 against a 4.7 lifetime badge built from 15,723 ratings, and 99 of the 100 are verified purchases, every one from the UK. But the small cluster of unhappy buyers mostly report the same thing, their fish stopped eating, and it lines up with a change the manufacturer confirms. We read all 100, counted who said what, and worked out whether the new sticks are still the safe default for a British garden pond.
Less Is More: What Tetra Changed, According to the Bag
The bag on this listing is the 780g size, marked 7 litres on the front, made in Germany, carrying the "with natural ingredients, no added preservatives, no colourants" roundel. A second listing image puts the old and new tubs side by side under the words "Less is more" and lists what the improved recipe drops: no added preservatives, no colourants, "same great results". The magnified sticks tell the story visually. The old ones are a warm brown, the new ones a pale straw colour. Mrs. A. Wright (1 star, May 2025) wrote that hers were a "different colour all together", which reads like a buyer who received the new recipe without knowing one existed.
The back-of-pack panel, also shown on the listing, gives the numbers. Ingredients are vegetable protein extracts, cereals, derivatives of vegetable origin, oils and fats, minerals and yeasts. Analytical constituents are crude protein 29%, crude fat 4%, crude fibre 2% and moisture 7%. Additives are vitamin D3 at 1714 IU/kg and citric acid at 274 mg/kg as an acidity regulator. Each stick measures 8 to 12 mm, and the feeding recommendation is at least two to three times a day, only as much as the fish clear within a few minutes.
Two things stand out from that panel. There is no fish meal in the ingredient list, so this is a plant-protein daily staple rather than a growth or colour-enhancing food, which is exactly how the five-star reviews treat it. And the "no colourants" line explains the paler stick: the old brown tint has gone, which makes no difference to the fish but is visible enough to unsettle a buyer who has used the brown version for years.
Five Buyers Who Blame the New Recipe
Five of the 100 reviews tie their complaint to the recipe change, and they are spread across the whole collection window rather than bunched at one end: May 2025, two in August 2025, February 2026 and August 2026. Four of the 100 say outright that their fish would not eat the sticks, and three of those four blame the new formula.
Dorris (3 stars, August 2026) is the most recent and the most specific: "it has quite clearly changed it looks different there is obviously a change to the recipe my fish won’t eat it anymore" (sic). Robin Calvert (2 stars, February 2026) reports a texture problem rather than a refusal, saying the sticks are "now almost impossible to break" and joking that it is lucky fish regrow teeth. That hardness complaint is the only one of its kind in the 100, so treat it as one pond's experience rather than a pattern.
The harshest review is Mr. Christopher Lee's single line (1 star, August 2025): "All my goldfish have died since getting the new food !" It is one review out of 100 with no detail about the pond, the water or the weather that week, so it cannot be pinned on the food, but we are not leaving it out either. Mr. A (1 star, August 2025) ends by asking other buyers to recommend an alternative, and SJ (2 stars, July 2025) thinks fish "used to the variety version" simply preferred that one.
Set against that: 32 of the 100 reviews say the fish love, devour or go crazy for the sticks, and they are spread across the same 16 months, 15 of them posted in 2026. Whatever the new recipe did, it did not put off most ponds. The risk the complaints describe is real but small, and you will know within two or three feeds whether yours is one of the five.

A floating daily staple for goldfish, koi, orfe and rudd that 86 of the 100 most recent UK reviewers rate five stars, with a cleaner filter as the bonus.
What 86 Five-Star Buyers Keep Coming Back For
Most of the 86 five-star reviews are short, and they say one of two things. 32 of the 100 reviews say the fish love the sticks (or go crazy for them, or devour them). 35 mention price or value, and 34 of those mean it as praise; the one exception is J. Tancred's short-date complaint, covered further down. Delivery, packaging or service get a mention in 16.
The fish named are the ones a UK garden pond actually holds. Koi come up in nine reviews, goldfish in seven, and four reviews also name orfe, rudd, comets or a chagoi called Bert. Roldy (5 stars, October 2025) keeps koi: "This is the only thing my koi carp will eat lol, we've tried other sticks and they wont even touch it." (sic) Mrs M (5 stars, August 2025) keeps goldfish, thought they were content on their old food until she tried these, and now reports "They go crazy for them."
Nine reviews describe themselves as long-standing or repeat buyers, and three of those are recipe complainants: Dorris, Mr. A and Robin Calvert all say their fish used to love the old sticks. The other six are solidly positive, and one Amazon Customer (5 stars, July 2025) puts an age on it, feeding koi and comets that are "some very old too, nearly 40yrs" on this brand. ASF (5 stars, May 2026) adds a benefit nobody else mentions, that the sticks get the fish "out from under the plants too so you can see them", which anyone with a lily-heavy pond will appreciate.
Tetra's "No.1 Fish Food Brand" badge on the listing cites Euromonitor retail sales data from 2022, and the reviews read like a brand buyers default to rather than one they researched. Steve (4 stars, June 2026) sums that mood up in three short sentences: it is worth buying, Tetra is a reputable brand, the fish like it.
Floating Sticks, Clearer Water and the Flake Comparison
Seven of the 100 reviews mention that the sticks float, and six mention clearer water or less waste. The two points are connected: a stick that stays on the surface gets eaten rather than rotting on the liner, which is the listing's "clean and clear water" promise in practice.
NewSteve50 (5 stars, October 2025) is the most useful review in the set because it reports a measurable change: "Fish eat it all because it floats rather than dropping to the bottom." With a bio and UV filter running, that reviewer has been able to halve how often the filter and pump filters need cleaning. Miss Marple (5 stars, July 2026), who keeps a ghost koi and a butterfly koi alongside her other pond fish, makes the comparison most UK pond owners will recognise: "there doesn’t seem to be waste. I had a lot of waste when I used the flakes."
The listing calls them fast-soaking, and in a British summer pond that matters at both ends: the sticks soften quickly enough for smaller mouths but stay afloat long enough for the fish to find them under the lily pads. Philip Brady (5 stars, June 2026) calls it "Great food for my koi and orfes in the summer", which is the right framing. This is a warm-weather staple. Once the pond cools in late autumn and the fish stop feeding, the bag goes in the shed until spring, which is another reason to check the best-before date when it arrives.
Stick size is the one open question, and the reviews split two against two. El (3 stars, March 2026) found the 8 to 12 mm sticks "good for the bigger ones" only, and Sarah Linklater (5 stars, September 2025) says her fish "are to small and prefer live food" (sic), though the snails enjoyed them. Against that, simone bowman-whiting (5 stars, July 2025) says her baby fish "loved the sticks" and grew fast on them, and Liz Parsons (5 stars, June 2025) found them "not too large" for her smaller fish. If you are stocking a new pond with fingerlings, buy these alongside a flake rather than instead of one, and drop the flake once the sticks are being cleared.
Short Dates, an Old Label and a Bag of Dust
Seven of the 100 reviews are one star. Three of them are the recipe complaints above. The other four have nothing to do with the fish at all: three are about freshness and one is about the state of the bag.
Bunny (1 star, August 2025) received a pack in the old livery: "Old label design so old stock and very short best before date." With only a few months left, Bunny did not expect to get through the bag in time. J. Tancred (1 star, October 2025) had two months to the best-before date. Phillip Scaldwell (1 star, August 2025) went further and questioned whether the box was a Tetra product at all, reporting no date code, lot number or manufacture date, though that is one review and nobody else in the 100 repeats it.
Three short-date reports in 100 is not a pattern that should stop you buying, but it is worth a 30-second check when the parcel lands. Both the transition note on the listing and Bunny's "old label" remark suggest older-recipe stock was still moving through the supply chain in 2025, and older stock carries shorter dates. If the date is closer than the months you will be feeding, return it. A 780g bag lasts the summer in Work jumper's pond and "quite a while" in Philip Brady's, so you want the full shelf life.
The last one-star is S GRAINGER (August 2026), who found a lot of crumb in the bag: "I feel I've paid for powder rather than product." No other review mentions powder or dust. The listing close-up shows an open, puffed texture, so some breakage in transit is normal; a bag that is mostly crumb is not, and that is a return rather than a shrug.
Which Pack Size to Buy, and Our Score
One disclosure before the score. Amazon pools reviews across the Tetra Pond Sticks sizes, so the 100 we read include buyers of other packs: Andrea Robinson (5 stars, May 2026) was pleased with "2 x 1 litre containers", A2010 (5 stars, July 2025) describes "Huge pots x2", and R. L. Pollard mentions a 100g size. This page is the 780g bag, which the front of the pack rates at 7 litres. Mooseblaster (5 stars, July 2026) puts the case for it in one line: "Bigger pack and better value if you have a decent size pond." The only packaging wish in the 100 comes from Work jumper (5 stars, July 2026): "Would be nice if food came with a small scoop". There isn't one, so keep an old yoghurt pot by the back door.
Now the working. The 100 most recent UK reviews average 4.59 against the listing's lifetime 4.7, a gap of about a tenth of a star and not one we would read as a slide. The largest failure cluster is the recipe change at five reviews in 100, well under the level where we would start pointing readers elsewhere, and the next largest is short dates at three. Against that sit 86 five-star reviews, 32 ponds where the fish love it, and six happy long-term buyers.
We score the Tetra Pond Fish Food Sticks 780g at 4.5 out of 5. It loses half a star for the transition muddle: the listing cannot tell you which recipe you will receive, a few ponds have rejected the new one, and old stock has turned up with short dates. Buy it if you keep goldfish, koi, orfe or rudd in an established UK pond and want a floating daily food that keeps the filter cleaner than flakes. Check the date on arrival, watch the first two or three feeds, and if your fish turn away you will at least know why. Check the current listing for today's price and stock.
