Hello, I have a 20 gallon, live planted, mixed sand/gravel tank with a sorority of 4 female bettas, going to up the number to 6-8 :D But I was wondering if a school of 5-6 zebra danios would be proper tankmates for them. I've researched quite a bit and some sites say they are quite compatible while others say that the Danios might nip the Bettas' fins.
So I'm not all too sure if I should place them together or not. I've also heard if you kept the number to 5-6 Danios, they tend to keep to themselves so hopefully they won't nip the bettas' fins? What do you guys advise me to do?
(Also planning to add otos to the mix or maybe a few cories once I get some more algae XD)
