I just posted a review that described my issues. To summarize, I had two small to mid sized Orandas in 10 gallon tank. I used one three day feeder for a five day vacation. A few days after I got home, the fish started getting fin rot. One eventually died and the other lost most of it's tail and dorsal fin. Not certain, but I am suspecting that too much food was released in my 10 gallon tank for just two smaller goldfish. The product descriptions says it can feed 15 to 20 fish for 3 days, but doesn't provide much guidance beyond that.
I think it would be better to have the tablets feed 5 to 10 fish and then you could double the quantity, if needed.
