Used for a 10 day vacation and came back to all my fish and snail dead in a 20 gallon tank. Killed my 6 glow fish and snail.

Our goldfish was about 3 years old, fairly large, we went away for 3 nights and this feeder killed her, or starved her, not sure which but it was definitely this feeder.

Fish didn't like this or it didn't disintegrate so they could eat it

I get these for both of my tanks. I have goldfish and tetras in 1 tank and guppies, Cory catfish and a rainbow shark in the other. They all love these food blocks. It makes cleaning so much easier,less mess than flakes

We have used this on both of our last trips. Both times we have come back to dead fish, and a barely dissolved block. Poor fish starved to death! Ph was within norms, air stone circulates just fine, temp is an even 72d, tank is 10gallons. In fact, from our trip over labor day weekend, there is still a chunk left (it got knocked under this decor during my cleaning of the tank as I took the photo). Why in the world is this much left 3 weeks later? Been watching it slowly dissolve away, never releasing actual food. Dont trust unless you too want dead fish.

Lasted a few days. Fish seemed to like it just fine.

Went on vacation for 5 days and fish survived. Worked great no fish died!!

It is very good quality food for my fish and very affordable.
