I bought 6 4-5" orino's, transported em home 1 hour in a cooler. two turned upside down in the cooler but seemed to be breathing fine, after two hours in my tank they seem to have died and a third just turned and seems to be goin out. wtf is going on? I have never had any problem like this before. are these fish just that finicky? ive had cichla in the past and never had this problem????
