Will the poop and other waste be overwhelming like goldfish?
Oh and I just figured that the gravel could be sharp on their fins. I just brought home my first one. It's in a 2.5 gallon tank right now, but I'm pretty sure that I'll be advancing to a 10 gallon soon.
I have had to put one of my bettas in a bare bottom because he kept trying to move the gravel at night, and no they don't tend to unless you feed them to much/to often
