I have a 20 gallon long that has 1 pleco, and 1 silver dollar, both of which are out growing my tank so I'm giving them to my friend because he has a way bigger tank. I wanted to get cichlids, but my tank is too small for the ones i want (convicts), so that's not happening :sad . What I want is an attractive schoaling (sp?) fish that would be fun to watch, most likely neons, and another medium size fish (2 to 3 inches). and nothing that would be too senstive to water conditions. My question is what fish do you guys recommend and how many to get, THanks.
