just got a new tank 20L I was wondering about who i can fit in there. I have 4 platy's I'm cycling with, and I'd like to have a school of 6 julie corys, a school of 6 tetras(side note: i had been intending to get flame tetras but it has now occured to me they're in the same color scheme as my sunburst platys so i want to find a species in blue or green, etc. any suggestions would be welcome) Would it be overdoing it to add a bushy-nosed ancistrus. Thanks for the help in advance!
