So I have a 55 gallon that I want to start stocking. Its been set up for over a year. It currently has 2 plecos which I believe are a bristlenose and a common and also tons of snails. So I think I either want to do fancy goldfish or angelfish. Either way the plecos will probably get rehomed. So my question is about the angels. How many could I do in the tank? I also want a schooling fish so suggestions and how many? I also would like otos and yoyo loaches how many of those could I get? Are there any issues with the fish? Im also going to plant the tank. Thanks!
