i watch the betta all the time as i thought it would be him, but hes very quiet, he keeps himself to himself, he doesnt bother with any of the fish.. thats why i then treated them for fin rot.
i know i will need a bigger tank for the balas, they are fantastic, and i have every intention of getting a bigger tank for them in the future..
the guppies tails dont seem to get better at all, they have been like that for a wee while now, with no repair
