That's a long time. There was one instance where I dripped a fish for three hours. A wild caught butterfly taken in 55 degree water off Rhode Island. Temp acclimated up to mid 70's. It lived for a couple of weeks in an fowlr, got it eating brine shrimp nauplii.I just posted on a thread recently where a person dripped their clownfish for two hours inside the bags they came in.
So two hours inside some dirty bag water with no flow, no way of good oxygen exchange.
Both fish died.
I can’t 100 percent say with a fact it was the drip but you can’t convince me it is beneficial to keep a fish in a tiny amount of water like that without flow.
If you want to drip, that is ok but do it safely. Do it in a bucket of new water (ideally, especially if shipped) to match with an airstone or at least agitate the water now and again if it is going to be a long drip. Otherwise keep it 30 min tops by adding scoops of water instead.
