Update: I moved all the fish successfully to the new tank upstairs. Everything was going good until we found a clownfish on the floor dried out one morning. A trip to my LFS and a Red Sea DIY net cover and that won’t happen again.
After having good success with short untreated observation quarantine periods my luck seems to have run out. I introduced a yellow tang who I thought was disease free. I had my suspicious (light white specs only on pectoral fins) about this fish but didn’t have Cupramine or Prazi on hand so I just left him. A few weeks passed and he looked good as the specs had faded. After introducing him, my royal gramma started looking beat up the next day but also rubbing on rocks. By day 2 he looked worse and rubbing more. At this point I figured there was a good chance something was in the tank from either the tang or the stress the tang had brought upon the other fish as he was the first semi-aggressive fish. Since I hadn’t treated any of the fish before introducing them it could have been either.
Going forward the only way to ensure my tank was disease free was to leave it for 8 weeks in fallow. This also meant I needed a new quarantine setup. The current one was small and very difficult to do any work or even add/remove fish. I quickly set up a couple of new 40g quarantine tanks and used mostly water from display to fill. I took rock I was confident I wouldn’t be using in the DT (well definitely not now) to make sure I didn’t have an ammonia spike.
Overall, I am happy the way these turned out and they will be now used every time I get a new fish. I will be treating Cupramine and Prazi for 4 weeks before anything enters the DT.
Catching all my fish was a nightmare, it was difficult and stressful for them. I had to remove nearly all my rocks, even the ones in the picture below besides the large one on the left.
After having the tank now set up for a couple months I realized that the aquascape I had didn’t allow for coral growth in the future. Even placing a few frags was difficult with some of the shadows I had. Here is the new aquascape. I am much happier with this. There is almost no room for detritus to build up and leaves lots of good space for coral placement. The only concern I have is places for the fish to sleep.
I did move a couple pieces of GSP up in the sand to give it some color. I am hoping by placing on the sand they will be easy to control and cut back as needed. I have no intentions of moving these anywhere near the aquascaping or glass.
