What size QT

[Neptune 555]

I was thinking that I would QT a few fish together at the same time... In a 20 gallon QT can I place one small blue hippo tang and 2 small percula clowns together?

What size is the tang? If it is under 2", it should be fine.

IMO people grossly overestimate the size tank they need for a QT. Any fish under 6" can be in a 15g (30") tank for 2 months without issue.

I guess I am looking more at it from a filtration (and ammonia) standpoint. With planktivores, I completely agree. But with herbivores with big appetites, it can be tough to maintain water quality in smaller tanks.

I'm with Peter on this, I've used my 20L to QT just about everything and usually have 3-5 fish in there at a time. Just make sure your sponge in your filter is well seeded.

I used to think it was cruel to have a 4in fish in a 20g that changed when I put in a 4 in fish that was in qt for 4 days in my dt and he had velvet. I have 5 fish in a 20g qt now and they seem happy for 4-6 weeks.

I have two quarrantine tanks, a 20L and a 30L. Most fish, either singles or groups, do fine in the former. Recently ran a quartet of butterflyfish through and they managed fine; housing a Naso now. The larger QT is reserved for touchy fish like an Achilles tang or group of anthias. I always keep a few bags of those ceramic bio rings in my sump; more than sufficient to manage a group of fish.

The important thing to remember about a QT tank is to keep up the water quality. I've QT'd and even treated multiple fish at the same time (with no filtration) in a 20g tank several times before.

I just store left over DT water in a tote, add the medication to the water in the tote, and change out about a gallon per day, or more if needed...

Never thought about this idea...makes really good sense. You don't have to think about how much meds to add after a water change. Thank you so much, best advice I've seen/read all year!

No problemo... Just remember to keep the treated water covered, and at room temp so the salinity and concentration of the medication doesn't change from evaporation...

Best of luck!!!
