I have a 20 gallon aquarium which is cycling right now. Would it be ok to put: 3-4 guppies, 2 platies, 1-2 dwarf gouramis, 6-10 neon tetras, and 1 small algae eater? Will all of them be ok to each other, and can a 20 gallon take that many fish? Like are they all compatible? Will there be any chasing around and stuff?
