I have my 1 and only "nice fish" tank the cory tank with of course the famous Bettadora. it's 20 gallons and 12 corys, 1 "bettadora", and now 4 very tiny what I feel are yoyo loaches( but I could be wrong, they were labeled Angelicus Botia but from every google search the look doesn't match..they look more like the yoyo loaches my bichir ate). Anyway I put them in the 20g for them to grow out in but I have decided I really like them and how they interact with the cory's and after long thought I really think at full grown they will still be easy food for the bichir so I now plan to move them all to my unused 55g. I will transfer over soon but feel that with that tank it'll look bare and wondering does anyone have ideas for middle or top swimming fish I could add to the tank? Or should I just add a few other groups of different loaches? What would you guys do?
