I started my tank up the beginning of December. Finished the initial cycle and added my first 2 fish a pair of small clowns. A couple weeks later I purchased 3 fish from Liveaquaria 2 of 3 arrived dead. The lone survivor was a powder blue tang. He of course had ich and I introduced it into my DT. If I knew then what trouble lied ahead, I would have definitely started with a qt. I told my wife I needed one before I started adding fish. She said "We are not spending more money on another tank, have faith they will be okay" HAHAHAH! I went hypo in my dt for over 30 days and everything seemed to be good. I added some more fish while I was hypo thinking it would be a good way to keep from introducing any more parasites. Everything was good fish appeared healthy. Tank was maturing, I started adding corals. Corals filling out nice. Well the ich came back on the PBT. I decided I was going to feed heavy frozen with Vitachem and Chelcon and hope his immune system would fight it off. Well this last month or so it had gotten a lot worse. So I bought some Polylab Medic and a diatom filter. I haven't introduced any new fish in months. The same time I started dosing medic I added a Bubble coral. The ich didn't seem to be getting any better. So I talked my wife into the qt. Got it set up with copper power at 2.0. I stopped with the medic and diatom. Within 24 hours of stopping the medic 4 fish died. I'm thinking that maybe the bubble came with Brook and the Nedic was suppressing the Brook. It took out my PBT and one of my clowns. I mean it was fast! I'm thinking the PBT's already compromised immune system let the Brook take hold easier. I also lost the other clown and a coral beauty that weren't even really showing symptoms. I have my One Spot Foxface in qt rn. He is in rough shape barely eating but still hanging on. I still have a Flame Hawk and Melanurus in the DT. Spent hours trying to catch the dang Flame Hawk. Broke my Birdsnest in the shuffle. Couldn't find the Melanurus. I'm feeling so defeated men. Neither the Flame Hawk or Melanurus are showing any symptoms but I'm just ready to get them in qt so I can get rid of this crap and start fallow period. On top of that I been struggling with red slime and stringy algae. I'm assuming cyano or maybe dino. I dosed chemiclean today after I gave up chase of the Flame Hawk. For anyone reading this thank you for "listening" to my rant. There has been times in this hobby I have felt SO GOOD and accomplished but days like today make me want to just quit it.
