Hey folks, gonna try to keep this short and direct. I believe I have some form of bacterial issue in my DT, I'm assuming it's Velvet, I lost one small Firefish yesterday, and the other fish look like they're on their way out... Started with tiny white spots on fins and body a couple of weeks ago, I assumed Ich at this stage but wasn't positive, as I felt the spots were too small ... it now has developed into chalky mucus coats (2 Clowns, 1 Firefish, and 1 Royal Gramma). They have all been displaying flashing, sand rubbing, and rock rubbing behaviour for a couple of weeks also, but its intensified in the last 48 hours resulting in 1 death. The Royal Gramma looks in bad shape, with some damage to his fins and chalky coat, the clowns just look chalky now, the other Fire fish seems okay for now, but treating it anyway.
Current signs/symptoms:
2x Clownfish Tiny white spots, that come and go every 48 hours or so, are displaying tilted swimming at times, and have chalky white film, no other symptoms, still feeding.
1x Royal Gramma Tiny white spots, that come and go every 48 hours or so, has been scratching against the sand and rocks for 10 days maybe, has a chalky film over his body, and damaged rear fins, it has still been feeding up until today.
1x Fire fish no symptoms at all, seems totally fine.
1x Fire fish (dead) was rapidly breathing yesterday, and lethargic, died over night (I gave him a fresh water bath, but was too late)
I have removed all the fish from my DT and set up a 20ltr QT in another room, and I gave all fish a 5min fresh water bath at the temp they're used to, which I'm planning on lowering the salinity to hyposality levels over the next week, and it's also being treated with copper based medication (NT Labs Marine Anti-Parasite; targets Cryptocaryon, Oodinium and other protozoan parasites). I have the following questions for each tank:
Quarantine tank (QT):
1a. I'm assuming I'll need to do water changes to keep on top of the ammonia, will this reduce the copper levels when I do that? The medication I'm using states to add 0.5ml every day for 11 days. So I'm unsure if that every time I do a change, I'm removing too much of the copper? So looking for clarity there. Instructions don't say anything about water change effects.
1b. Should I simply stop the copper treatment at 11 days, or continue it for longer? I guess if I stop, then continue with water changes, I'll slowly dilute the copper back out to get them ready for going back to the DT?
Display tank (DT):
2a. I have the followinginverts still in there (1 cleaner shrimp, 1 blood-red shrimp, 5 small hermits, 1 small emerald crab, 4 nassarius snails, and 2 Konch snails). My assumption is to simply maintain the DT as normal, and just reduce feeding a little?
2b. I installed a UV Steriliser yesterday in the sump (10w, with quartz sleeve and bulb, by Deltec, pump is on the lowest speed possible to target fish parasites), with this running, would a 45 day fallow period suffice? I see a lot of mixed discussion around 45 days vs 76 days.
2c. I have just turned the lights off for now, any issue with keeping the light off? My thinking is it will help with algae from taking hold... but the reason I ask is because I' wondering if that might starve the inverts?
2d. I'm currently treating the DT with Polyp-lab Medic, should I just stop with that now? Any value in finishing the course? I'm about 10 days into the 20 day course (my DT has no corals, just FYI).
Thanks in advance for any/all advice, I've never done all this before, I'm still new to the hobby; just trying my best to do right by the fish at this point! I thought this would be a nice relaxing hobby
