After a hard lesson learned, I set up my very 1st Qt. It’s a 55 gallon tank.
5 days ago I bought a 55 gallon tank and stand, added 22 lbs of LR and a couple of cups of gravel from an established tank, added 20 gallons of water from the same tank and the rest with new water plus 2 sponge filters that was sitting in the same tank’s sump for over 2 months. Also added a Marineland Penguin 350 for filtration and 2 bottles of Bio-Spira.
Yesterday I added 4" Blueline Angelfish and a 6" Crosshatch Trigger. Acclimated them as usual and in they went.
Immediately the Trigger went to hiding and the Angelfish was checking him out right from the start but later in the afternoon, the Trigger was out and no issues with the Angel. Both eating mysis shrimp and krill.
I know that you are supposed to add one fish at the time into QT but I thought that the tank was large enough for both fishes and both are supposed to be pretty shy.
Plan to observe them for a while, if any of them get sick, I’ll take out the LR and treat the tank.
Hopefully they won’t and 4 weeks from now they will be transferred to my 300 gallon tank which is going fallow. By the time the QT fish comes out, it’ll be fallow for 10 weeks.
