IMO the tank to small and you would be best of swapping them for more threadfins.The thing is my PH is 6.4 and my water is very clear as i have fluval 2 plus internal running on the tank with weekly water changes of 25%. Also they are shoaling with the threadfins..... I'm guessing this is because there's only 2 of them.
I really would like to keep them. They have loads of room and they seem to have be-friended just about any fish in the tank(except the cories which don't like anyone because they are grumpy old men)
