omg ur comments with all these feeder fish are making me laugh so hard! ahahahahah. But a planted tank and about 20 neons would actually look pretty nice! you could do a non aggressive tank if you wanted. If not i would go with a pair of convicts. And guess who just got 16 wild convict babies? Me! so if u want any pm me and i can send you someneon tetra... and dont ask if u can keep two in a 37g unless u want to stunt their growth
