What kind of fish do you have?
I have 2 Orandas and 1 fantail, the orange one passing through the shot (Molly) is the largest at around 3 inches. The other Oranda, is a red cap, he (Jack) is only about an 1.5 inches and the Fantail (Jill) is about 1 inch. They are all pet store rescues, this will be their home for about a year than off to a 75 gallon tank forever .
There are also 6 permanent resident snails in there, 2 Gold Incas, 2 Japanese Trapdoor and 2 tiny Assassin snails.
