Just to let you know i got one yesterday that i had my eye on for 3 weeks now. I figured that he was ok since he was at the lfs for that long. I acclimated him between 4 and 5 hours just to be safe. I mowed the lawn, cleaned the house, made dinner and then my 5 gal bucket was 3/4 full from the inch of water it started out as. The first blue i got died in a few days and never even really moved in my tank(didn't acclimate him for more than 30 min., plus it was a new tank) This guy has been all over the place since he has been put in.
