So I have a spare 10 gallon aquarium now (I moved the bettas into their own two 5g tanks because I felt the divided 10g was stressing them) and want to plant it and stock it. I'll probably re-cycle it (if that's possible?) because I don't know if the bioload of 2 bettas would make the BB strong enough to handle what I'd like to stock. I've been looking at different small fish and came upon two I really like: scarlet badis and the celestial pearl danio. I've been reading on the badis and think they are a little too advanced for me, so maybe I'll try them sometime down the road. The celestial pearl danios are gorgeous though too! So I've been reading about them and think I'd like to try them. I read they are shy when in small groups, so how many would be too many to keep in a 10 gallon planted aquarium? I'd like to see them active and happy. If you have any tips on caring for the species, such as preferred foods or eating habits, tank mates (if my tank is big enough), or anything please do! I'd like to know all I can about them. Edit: would I be able to mix some of these with a sparkling gourami or two in a 10 gallon?
