Well i was thinking that but.Adrinal said:crap, I messed up my post... was a long one too... ahhh
Its too late to type it all now. but here is a quick recap:
1) Less cat fish of the plec nature. 2-3 from one of the larger growing species is enough.
2) I think its the cardinal tetras you have 20 right? make it 50. This is a dream tank where shcools of fish should school. So have AT LEAST one of your fish choices be a school and not a classroom.
Thats all I can add for now sorry.
