Hello, I am planning to add new fish to my 20g long freshwater setup. So far I have 1x clown pleco 5x flame tetra 4x shrimp 3x cories 1x gold algae eater 3x marbled hatchetfish I am planning to add 6x lemon tetra 6x royal tetra Can someone please tell me if I am overstocking or if fish aren’t compatible?
Just from looking at it, your tank sounds to be maxed out. You really can’t have more than 1 school of fish in a 20 gallon. There isn’t enough room. Clown plecos, although stay small, produce a ton of waste. I wouldn’t recommend for a 20 gallon. The tetras are fine in a 20. Shrimp are fine but will probably have a hard time populating. Cories need 4 or more in a shoal. The “gold algae eater” might be an albino chinese algae eater, can you post a picture of it? If it is, it is not suited for your tank and get very aggressive as they get older. The marbled hatchetfish are good but need groups of 6 or more.
