Tetra Vacation Food Slow-Release Feeder Block For Tropical Fish, 1.06 oz

I was going on a couple weekend trips in a row so I bought one for my 10 gallon tank. The tank is home to four guppies and three neon tetras and the fish all seem to like it. The guppies tend to eat at the surface and the tetras around mid tank level so I put it on top of some decoration around mid height. I’ve seen both species eat from it so I’m very pleased. I like it better than the extended releasing feeders already. My snails like it too much however! The greedy little things have been moving it around and I swear one of them hasn’t left the brick for a day! If you have mystery snails I would recommend finding a way to keep the block out of their reach. I figure with my thieving snails that it won’t last the full 14 days (by no fault of the manufacturer!) so plan accordingly.

Kept our fish alive while we were on vacation!

I bought 2 five day tablets to do a trial run in each of my 2 tanks. They were put into the tanks the day after a detailed cleaning. On day 2, I was left with 2 cloudy tanks the morning after dropping the tablets in them! Also, the fish were almost entirely disinterested in the tablets (I have guppies, tetras, snails, glo-fish and rasboras). By day 3 both food tablets were showing fungal growth which became worse with each passing day and acted as a barrier to the fish actually accessing the tablet! Another reviewer on this page who took pictures of his tablet actually shows the fungal growth (it starts off as a whitish mound) in his tank Only the snails in my tanks seemed interested in feeding on the tablets but I noticed one snail that was eating it keeled over & died post feeding not 1/4" away from the tablet!. Simply put, it was a disappointing experience and I will have to seek another solution to finding a way to feed my fish while on vacation. I was hopeful that this product would work. Frankly, I am surprised that some folks here have anything positive to report about these food tablets! Nevertheless, the negative reviews all say the same thing: cloudy water and many fish don't go for it.

we were going on a 5 day trip out of town and got these for our goldfish tank - tried it the day before and a couple of the goldfish went to investigate - one of them ate the whole block and later passed away from it while it is a great value for the money - recommend putting it somewhere the fish can't get to it

I like these fish feeders so much better than the white chalky ones that seem to always leave a white residue in the tank. I break a single 'feed cake' into about 5 or 6 pieces and drop them in different spots so that fish can easily feed on them wherever they are. They ARE slow release, so the food itself is dispersed over a period of many days. I have five guppies, two neon tetras and two algae eaters, so one of these feed cakes lasts about 10 days. An added bonus is that, if you have unwanted snails like I do, you will find them collected on whatever chunks are still left over, and just 'fish' those snails right out of the tank when you get home.

I don't know if the formula changed, but, my fish didn't touch it. My fish only eat this brand of food and they have had weekend feeders before-only ever this brand- so, I don't know.

Exactly as shown, bigger than I expected

I have a 50 gallon tank with 5 black neon tetra's, 7 emperor tetra's, 2 octo catfish, 2 cory cats and 4 amano shrimp. It had only been set up for 3 months, so the tank is not over populated. I threw one of these blocks in and we left on vacation for 30 days. Since its just my wife & I, there was no one else to take care of the fish. I figured that the tank would be an entire loss when we got back. Or just as bad, the evolution of an aquatic "Lord of the Flies" society would take place. But much to my surprise, when we got back, the entire block was gone and only one Cory cat was missing. And he was having trouble before we left, so I think the abandonment had little to do with his demise. And I am sure his flesh went to the greater good in an underwater repeat of the infamous "Donner Party" banquet! In any case, when we got back, everyone looked fine but a little thinner and slower. I think the secret to this extreme, but successful test of the feeder block lay in the condition of my fish before we left. Since I knew their diet would be restricted for an extended period of time while we were gone, I really fattened them up on frozen brine shrimp, daphnia, and blood worms in addition to multiple daily feedings of flakes and pellets. I let them pig out for a month. So before we left, they really had that pudgy cheeked, bubble butted all American fast food glow going, just like that loud jolly twinkie eating girl next door. So in my opinion, this gel block worked great! But don't rely on it alone. Fatten up your fish before you go!

It’s not worth buying those white feeders, we find they have left the water murky and we have had some casualties. We have been using the Tetra feeders for at least 10 years. It’s good how it slowly feeds flakes into the water or the fish nibble the block. If you don’t have a full tank of fish we cut the block in half.

I received it damaged. It was squeezed into a small box in a very bad way and the funny part is I can't request a return or a refund

Does the job....just make sure the plug doesn't get stuck under any rocks/ornaments in the tank....

Muy útil si sales varios días de vacaciones, puedes tener la tranquilidad de que tus peces tendrán alimento disponible. Lo he usado dos veces y nunca he tenido problemas.

Kept my fish fed and happy while I was away. Dissolves slowly and doesn’t cloud the water.
