So i bought 12 male hap\peacock cichlids from colorado they were all good looking fish in nice looking tanks. The guy i bought them from put two per bag with yellowish water. im guessing to help with the transport. they were carried in a styrofoam box all double bagged. I drove them home to iowa a 10 hour drive and then straight into the tank to acclimate. so less then 12 hours in the bags. when i released them i found three dead and everyone else acting very weak. The fist thing all the new fish did was go straight to the top and gasp for air. acting like they might have been oxygen deprived. I ended up losing half of the stock i bought. do you think the elevation change had anything to do with this? maybe the two per bag? Any thought may help. Wondering if its my fault, breeders fault, act of god maybe...
