Didn't want to make another board when there's already something similar, so here's a question:
My sister's (possibly my) betta makes very small bubbles around the tank (not very clustered, just sort of outlining the tank). Do bigger bubbles mean a happier fish, or is small & big the same?
I'm glad he's finally making a bubble nest, though, because he wasn't until we got him Hikari Betta Pellets! That sounded like an advertisement, but I'm serious! Flakes do NOT work for Bettas...at least none of my bettas.
