I'm running a 20 long planted... 9 watt UV co2 injection fluval 205 water changes 30% twice weekly i currently have 2 Otto 2 angels and 2 pairs of cherry barbs ..... i was wondering since the angels will eventually outgrow this tank how many cherry barbs could occupy this space total I'm not looking to breed and would like to have a moderately planted tank i just ripped out my old plants due to a low nitrate slime algae outbreak
