Do they get along? I have a 20 gallon tank. I waited for algae to build and I have a good amount,almost too much since I have been busy. I did a water change and I'm about to do another. I have 5 red eye tetras and a powder blue dwarf gourami. I want a pleco for sure. Probably a bristlenose. I love Cory Pandas too, and would it be okay to be together in a 20 gallon? Also, what other fish get along that are intriguing to look at. I want one more fish of decent size and maybe another school? Would that be overstocked? This is my first tank so I apologise if this is common knowledge, but I would rather be safe and not make any mistakes.
