Bettas and shrimp?
I have a pretty peaceful male betta living in a planted 3.5 gallon. I used to have him in a larger community tank, and he did well with other fish (neon tetras, bristlenose plecos, platys, and peppered corydoras) though unfortunately I had to move him due to the current being too strong for his long fins. The only time he ever tried to eat or attack anything living was when our plecos had fry, but I'd imagine that isn't too surprising given their small size.
I was thinking of adding either some red cherry shrimp, amano shrimp, or ghost shrimp in with him, but wanted to get some opinions before doing so. Would the added bioload be too much? What size would I want the shrimp to be for them to have the best chance of avoiding being mistaken for food?
I have some anacharis, mossballs, floating hornwort, and a terracotta pot in the tank. Would I want to get some more plants so they'd feel safer? What sort of plants would be best?
