I would like to see a nice list that has a nice combination of fish and that can have some corys please dont give me overstaock posts just avarage stock for the combination of fish u are saying
I would stick with pygmy cories in a 12 gallon. Normal sized cories would be way too active and large for a twelve gallon. 6 Pygmy Cory cats and a trio of guppies could work quite nicely in a tank like that.
either a school of neons with pigmy cories or use it as a betta tank
id set it up to plant lots of plants and driftwood, that way you could use it as a Q- tank if you have to
