Hmmm.....I wasn’t there, my BF picked him up. I’m not sure what placing crossways in a vehicle means but it was in the bed of a truck...... it was transported in a 30 gallon plastic storage tub, with an aerator running the whole time. Water was from it home’s holding tank. She pulled him from her main pond last Sunday. She also added anacharis to the water with it, and she’s been treating it with Melafix for the past couple of days, she said because he was stressed and she thought he may have been bruised from being caught from the main pond. So, 30 gallons, 10” fish, 12 hour drive, but BF went to bed when he got here, checked on him when he got up just 3-4 hours later, and found the tail fin pieces, sent them to me ( I was at work) and I had him do a partial water change then, about 20-25%, cause I was worried she overdosed the Melafix or something (I’ve never used it so I’m not familiar with it). When I got home from work I inspected him and found the damage, did a water test and freaked out cause those numbers were so horrible did 90% water change (I know not ideal but I figured way better than those water perimeters.) I also added a double dose of stress coat to the water. I don’t have any ammonia lock on hand and the store that sells it was closed.
He’s still in the tub, because I’m afraid to add him to my pond. I’ve never quarantined a new fish in the 8 years I’ve been doing this.... I just don’t have the means for that. But I’ve never seen a fish look this bad!
