Hi all, first post here, hope to contribute over time, but for now, unfortunately I need some help please. Long time FW aquarist and in early June converted our 75g to a saltwater tank. fully cycled, through the uglies, everything is stable, etc…
On June 30 I added this Powder Brown Tang, and a few days later it appeared to display Ich. It has been a voracious eater and hasn’t scratched or shown signs of suffering.
LFS recommended PolypLab Medic and freshwater dips, which I did last week for 3 nights in a row, for 7 minutes each. The fish took it like a champ, and each morning the white dots were diminished, but by night the spots were back (maybe it was the lighting that made them show worse?). I also started treating the tank with PolyLab Medic on 7/5, per directions and did that for 13 days to no effect.
A couple days ago it started spending time swimming into the current of the power heads, and I caught it flashing once or twice. Also over the weekend, the Ich started looking more like Velvet, so I set up a small quarantine tank. It’s still eating like normal.
Tonight, it looked worse than ever before (see video), so I verified parameters and transferred it to the QT, and plan to treat it with Copper for Velvet in the AM; assuming the experts here believe this is the correct diagnosis and course of action. @Jay Hemdal TIA. These photos and video are from tonight prior to moving it to QT.
Here are details:
Aquarium Parameters: pH: 8.2, Ammonia: 0, Nitrite: 0, Nitrate: 0.25, salinity: 1.024, temp: 77.1, KH: 143.2, Calcium 420-440, NO3: 1-2, PO4: 0.25. These have all been very steady and checked 1-2x weekly. I use only RODI water and Reef Crystals salt. I do 5-10 gallon water changes every few days.
Aquarium type: Reef (2 clownfish and 1 diamond goby are unaffected, crabs, snails, few starter frags are fine)
Aquarium water volume: 75g
Filtration type: Fluval canister 406, no carbon
Lighting: 2 AI Hydra 32 LEDs
How long has the aquarium been established? 6 weeks
Other In-depth information:
Have you lost any fish to this problem yet? No, all other fish are unaffected.
Are any invertebrates affected? Not that I can tell (3 red-leg hermit crabs, 4 snails)
Respiration rate of affected fish (in gill beats per minutes, count for 15 seconds and multiply by 4): Too fast, couldn’t get a decent count.
Are the affected fish still feeding? Yes, several times a day, eating Ocean Nutrition formula 2 flake and frozen Mysis shrimp
What remedies have you tried so far? FW dips, PolypLab Medic
Here is the link to the YouTube video from tonight as well.
Many thanks.
