good for you- they take time-- i have a powder blue similar stuff- been transitioned to the display tank but stayed in a cave for 2 weeks and has a 180 gallon to swim! now finally he uses it! they are very fussy. keep giving him seaweed they love it!You bet. Consider what this fish I have spared no expense. He was drip acclimated to the QT tank. I have several pieces of PVC and I kept the lights off. This morning I peeked in on him and he was swimming around thank God. I cracked the blinds on to get a little light in the room and he went straight to chasing his reflection. I them slide some white paper under the tank and he’s now back to chilling out. He’s still eating Spiralina Brine so I’m really happy about that considering the appetite suppression that’s caused by CP. So far so good.
