My redtail thinks it's a tuna

[Dirty Pete]

Noob here. Got a redtail that thinks it's a fish.

It's a 27" juvenile redtail named Titus; my 9 year old daughter's pet.

Got it 2 months ago. Had serious mites from the store but got rid of those by thorough cleaning and hot water soaking of enclosure and contents - no pest strips or other med measures.

Titus is heathy and happy and growing rapidly. An avid feeder. He's always been a keener for a good soak (it's how he rid himself of mites), but in the last few days he's taken to the bowl, totally immersed except for his head, and stays there for 36 hours at a stretch.

This is worse than my wife and her baths.

Water temp is 77 night and 82 day, with ambient at 82 and basking at 92. Humidity is 50 - 60%. No skin conditions or unusual behaviors. He's mid way between sheds and has no trouble pooping.

Is this guy just a reincarnated water snake? I mean, I know boa juveniles like soaking, but this is ridiculous.

Does anyone know ANY reason why any juvenile might be soaking for such long stretches, other than mites, too-high temps, or too low humidity?

Will oversoaking harm him? Should I remove his water bowl for a few days?

(I did do a search here on the subject, but could not find any specific answers. BTW good site!)
