Thanks guys for your replies.
I got a 65g just for them. It is 36x18x24, so it's pretty tall. I think this should accomodate them into adulthood, if they survive that is. They're probably silver dollar size or a bit larger.
As far as I know they were quarantined. Now, they have a tank to themselves, so this is not an issue. Someone told be not to keep altums with any domestic fish, especially discus and angels, as they will make the altums sick. So, went with that and made it an all altum tank. Will probably add 3 corries in there and 2 albino bristlenose after I convert it into a planted tank. For now, it's barebottom.
Clayt, what pH are you keeping yours in? Mine came in with a pH of 6.4. I was trying to match that, tried a bit of peat, I have some mopani wood in the tank that's leaking tannins now and it should help with the pH. I also added a little of vinegar. Checked the pH today and it's 7.6. A bit too high, but will try to bring it down over the next couple of weeks. Oh, and I also put in 8g or RO water into the tank.
What is everyone using to lower their pH?
Once it is planted, I can maintain the pH at around 6.7-6.8 with CO2 injection and maybe lower still a bit with peat moss. I will see if I like that color of water.
They went into the tank by one o'clock this morning and by 7:30 all were still swiming. That's the good news.
