So i was pondering the ideas of getting a 20 gallon tank… How much can go into a 20 gal? I was thinking of guppies and corydoras, would a 20 gal be big enough for, say 5 guppies, and 6 corys? If so, could a school of (small) tetras go in there too? (Also what Cory species is your favorite/ would recommend?) Sorry for all the questions, I'm still really new to the hobby.
