About 5 days ago I bought 5 storm clownfish. 4 from a hatchery, another from a fish store that quarantined before selling. The 4 from hatchery are teeny tiny about an inch, the other one from different fish store, is bigger maybe 1.5 inches. So upon arrival, they all went through methylene blue bath bc of shipping for so long and were added to 20 gal sterile qt. Bc of them being so small, I let them settle for the night and the next morning started ramping up copper. The 4 babies from the hatchery are doing great eating well and taking copper well. But once I hit about 1.00 in copper power, the bigger one from the different seller, stopped eating and staying more than less on the bottom of the tank, still swimming, but sometimes laying there, upright, but almost like it's tired. So I contacted the seller and he informed me he treated with CP before shipping for around 10 days. So I figured I'd give this fish another day and see what happens. I decided to add spectrogram. Added it yesterday. Copper is at 1.50, and figured with them being babies, I'd raise it to 1.75 to 2 and keep there for 14 days, then transfer to another sterile qt. I know they don't have velvet, brook or anything else. I'm thinking that this fish may not be tolerating copper bc of previous CP treatment and have been thinking about pulling it from the tank. I have a few small 3-4 gal temporary tank from petco that I can put it in with a bubbler and heater, and do ttm, but I wanted advice first. I've never been successful with ttm. @HotRocks i follow your protocall, so I was wondering what your advice is or anyone else that has had this problem. I don't wanna lose this fella, I named her ms piggy bc of how it ate before raising copper. It's $150 fish also. The other 4, I'm actually quarantining for some else. I've been doing that a lot lately so that's why I've made multiple posts about multiple fish, incase anyone was wondering about that. TIA
