Velvet after 2 months?

[linus.chan]

Hello all,

So i quaratined a rhomboid and Tomini tang on 12.22.2018 and while i treated with prazi and antibiotics i did not treat with copper or CP as i had lost a few fish when trying to treat with copper.

I waited for 4 weeks, observed no signs of disease and released into DT on January 22, 2019.

Everyone and everything seemed to be healthy and happy.

Two days ago i noticed that my rhomboid had a bit of a tattered fin. Nothing serious and it did not affect its swimming. I thought nothing of it and made a note to keep an eye out.

This morning, nothing strange about the fish.

TOnight, my rhomboid (much more so) is exhibiting the classic "sugar" dusting of velvet. The tomini tamnk also appears to have some "dusting."

This is devastating. TO top it off tomorrow night i am heading out of town for a couple of days.

I have set up my QT tank, but needing some time to warm the water up.

I will be tresting with CP as i have ran out of copper reagents for my hanna checker. I don't think i can catch all the fish in my tank. i suspect i will most if not all of my fish.

Anyone have any helpful words?

I guess i really thought it unlikely that velvet could be dormant for this long.

Wrasse are really good at carrying velvet without symptoms. What happens is once the velvet is introduced into a display with more fish, that gives the parasite more hosts. So it can multiply much faster.

You may want to consider copper since you have wrasse. Most wrasse won't tolerate CP.

You could at least get your initial dosing going while waiting on reagents to arrive.

at this point i am just hoping i can catch the fish. i think i can catch the rhomboid as he likes to swim near the top. and i may have a chance at the tang. I don't think i can catch anyone else.

Anyone have any ideas on how radial filefish tolerate copper/CP?

^^^ can’t get any better advice

Filefish do well in all types of copper, CP and TTM. But of course your mileage may vary as there can always be a sensitive fish, so close observation is required.

Unfortunately @HotRocks nailed it this is very common. Observation doesn’t work, particularly with wrasse and gobies and fish not overtly parasite-prone

your in good hands with @HotRocks and @4FordFamily.

just spent the last few hours trying to catch the fish. aside from a full tank break down not sure i am going to be able to catch them in time we are leaving out of town for the weekend . Of course this means likely deaths. I am very upset at this point. I feel stuck, i don't physically have the time or resources to do a tank breakdown.

 

[linus.chan]

and i get that wrasses can be hard to use observation. but the other fish that i had in QT and which never exibited any signs was the tomini tang which is parasite prone.

 

[linus.chan]

is it possible that this is ich and not velvet? i ask for several reasons-

1) the fish is showing no other signs of velvet-.no flashing, no respiratory distress, hearty appetitie and after nearly 12 hours after i spotted the white spots it has not spread all over the fish.
2) the fish is not dead.

 

[linus.chan]

thi isn't changing my attempts to treat. i am going to do my best to save as many fish as i can.

So not sure what to make of this. But from all accounts, i likely overreacted.

All fish are healthy and without any symptoms. THe lights when i saw there were heavy blue so i must have mistaken the spots for velvet. I am relieved, but bewildered a bit as well, as i could have sworn they had the classic velvet symptoms, but in less than 8 hours, with normal lighting, no signs of any symptoms and then i had to board my plane to Chicago with the expectation that i would be coming home to several dead or very ill fish. Now a week later, no symptoms for any fish and everyone seems healthy.
