I know I’m not I’m just wondering if I can get another clown fish eventually after I figure out what’s happening. Also don’t the fish get covered in a powder like substance when it’s velvet?
No, clownfish are actually very prone to velvet (Amyloodinium). It is unfortunate that we call it velvet, since there is a freshwater disease by that name, caused by a different parasite that looks different (dust like).
They were different fish, also is there any way to just kill off all the parasite that’s in my tank and what should I treat the fish that I have now so he doesn’t get anything? I got prazi pro and have metroplex.
There isn't any way to control velvet in a tank that won't also harm any invertebrates that are present. Copper or chloroquine are the two best treatments.
Does velvet have a 100% mortality rate and is there a chance this wasn’t velvet because my other clownfish was acting weird just like the other one and not eating but all off a sudden he was back to normal with a big appetite?
Correct, fish won’t recover from velvet without some intervention like a treatment. While velvet does not affect every species of fish equally, it is pretty consistent for similar species, so IMO, one clown getting better on its own without any treatment rules out velvet. I can’t tell you what the issue is though….
When I quarantine fish I just monitor them for two weeks and see if anything shows up so would a fish that has ich or velvet show symptoms in that amount of time?
One last question, do you need to quarantine fish in copper for 30 days or is 14 days ok because on some threads I’ve seen they only quarantine for 14 days and also at dr reefs they only do it for 14 days?
30 days is much safer. Its complicated; but copper doesn't kill the resting tomont stage. 14 days of copper is short enough time that there still could be infective tomonts in the tank, and when you back off on the copper, they emerge an reinfect the fish. If your QT is stable, always go 30 days. If the fish are not stable (fighting, ammonia, etc.) and you need to get the fish out in a hurry, 21 days is pretty safe, as long as you take the fish out of the QT while they are still in a full dose of copper. 14 days is what they use for ionic copper, but that is harsher on the fish, thus the shorter time. With coppersafe and copper power, 30 days is the pick time frame (I often go 45 days).
