Hello everyone

I asked a similar question when I first joined in someones thread and now I can't find it. I have a 10 gallon tank that is established and doing great. I change out 30-50% water every Friday and sometimes a 25%
water change in between if I give them a treat that makes a mess..

. I currently have 3 glofish, one is starting to nip at the others so I know I need more to make a school. I also need a algae eater. Here's my dilemma I want Otto's and they like at least 3 of them..Glofish like 6..That would be 9 fish..Too much

? I want them to have friends and be happy but don't want a overstocked tank..Any advise or suggestions are welcome.
