Hi DaveW
I wish I could say, with any kind of certainty, that they would be fine, but I just can't.
The secret to keeping pandas healthy is still a mystery to me, even though I've had them for a couple of years now. When I first started with them, I don't know how many I bought before I got a small school to live. I would buy them and within a few days they would die. The next time one of the lfs I shop at would get some, I'd to the same. Eventually I collected a few that survived and they grew up and spawned.
That was another whole round of problems. One morning I woke up to find that every panda baby was dead, without any symptoms, but all the albino C. aeneus young ones in the same tank were fine. I never did figure out what happened there. Eventually, I got a nice batch of young pandas growing up. It's been a while since I've lost one, thank goodness!
On the other hand, when I moved in August, the panda tanks were among those that lost some of their beneficial bacteria and went through a mini-cycle. Every one of them made it through, even though it was a very stressful experience for them.
I said all that so you can see just how difficult they are to keep. Like I said, they are still a mystery to me. I can say for sure that they need a very clean and stress free environment to thrive. The do well in a tank by themselves, or lightly stocked with very small and gentle fish. I give mine twice a week water changes and add a dose of MelaFix at the first sign that they could be in any kind of distress.
Other than that, I guess luck could play a part, so don't take their loss too hard. They are difficult to keep, even under the best of circumstances.
