So, a couple weeks ago I bought a blue/red-orange platy at the fish store along with a black (with some white) platy.
What was really odd was that the blue/red platy hid for days. I honestly couldn't find it. I discounted it was most likely going to die... I was moreso looking for a body and each time was surprised it was alive. Maybe I'm a bit pessimistic, but in my experience if fish do not adjust well, and integrate themselves into the community within a day they seem to die...
Anywho, this platy hid for about solid 1-2 days. for days 3 and 4, she hid, but came out for food. By about day 5 she was coming out more, and after about a week she was just like all my other fish - a part of the community.
What I am wondering is what causes this snail-paced adjustment to happen to some fish? My black male platy was perfectly fine. I have not had this happen with a positive outcome before. And while something was going on with my tank, and many of my fish were dying, she still survived.
I always assumed this was a sign of lethal stress from the transition... that some fish just don't do as well as others, and the fish store may have not handled her properly (I believe I am good when handling my fish).
P.S. I think she just had babies recently. I hope some survive inside the tank. :)
