QT question

[Baldy]

I checked with bog als and I can get a 55 for a decent price. Have a canister filter and heater, light, ECT already so I think on going to get that and qt all the fish and do hypo. Let the tank go fallow for.12 weeks just to be damn sure. I i just have to decide if a 55 is big enough or if it's worth the extra 125$ to go with a 90. No 75s in stock unfortunately.
