So, I have this giant 700 gallon livestock trough that I use as a "pond". Right now I have 23 common goldfish, and a ryukin. I was thinking of another stocking for it. I've always wanted a giant gourami, and I never realized that the answer was right in front of me! My pond! I need to bump up the filtration on it a little bit. This most likely will not happen this year, but I was thinking about stocking a Giant gourami and 1-2 Common plecos, but then I don't know what else I could stock. The pond's diameter is 92 inches, and the height is 24 inches.
