I'll start the 50% water changes tonight. You don't think that it will bring the pH down too quickly and shock them, though, do you??
I didn't know that Platys need that much space, or else I never would have gotten them. I wish I had someone I could give them to, but I don't. I'm getting paid holiday pay/vacation pay coming up on one of my next pay checks, though, so I'll have to start looking into getting a bigger tank for them. Guess that means I'll get to go tankmate shopping, also
They'll have to wait a bit, though, while it cycles.
I know that bettas as tankmates can be hit or miss, but I'll be hopeful. I'll keep an eye, and if he doesn't work out, I have a tank for him to live in on his own. I've tried betta communities twice so far. The first one was great; he tried to school with my tetras, haha. The second didn't work, though. He got major fin-nipped
