So, I have two tetras now (for cycling purposes). When I have my tank cycled, I want to add more tetras and a cleaning animal. My question is three fold. 1. What kinds of tetras will school with Neon Tetras (other than other Neons)? Are there any fish that do really well with tetras? (I was thinking about a leopard Daino, would that be ok?) Finally, are there any good algae/waste eaters? I tried a Cory Cat but that didn't go well. I wanted to add shrimp. Would an Ammano and Ghost shrimp work and do well with tetras? My water is fairly hard (120-160). I wanted to consult with other experienced people after my trouble with my catfish petstore advice.
