Should i now treat with copper? please help.

[joaovieira]

As i told in a recent post (ich/velvet is back) i had 3 fishes in my reef tank (2 blenny 1 chevron tang), Only The chevron showed white spots. Yes indeed i quarentined all but did not treat them prophilatically in quarentine (i will nex time...)

All 3 fishes went to a quarentine tank and interestingly chevron tang do not shows spots anymore (for 2 days...).

Now what should i do?

1- treat with copper. please help me on the level (0.5 with blennies and a tang or 0.4 ?; how fast should i increase copper dose)
2- wait and see if lesions reappear (i know it is not very rational i just want to be sure i will take the best informed decision; i am afraid mainly because of blennies)


Thanks:thumbsup:

Its common for ich infected fish to be "spotless" for a while; then ich re-appears X100. Because no fish are showing spots and lots of things (bits of substrate, etc) are often mistaken for ich; I'd keep them in QT and just watch closely. If ich appears, treat. Let us know and we'll help as needed. If you go 6 weeks with no spots; I think you're OK. You have all the fish out of the DT, so I wouldn't return the fish for at least 8 weeks, regardless. Also, did the tang show spots in the QT prior to going into the DT? What are you using as a bio-filter in the QT?

MrTuskfish,
My quarentine has a skimmer and it is cycled. I QTined the tang and other fishes for 4 weeks, no treatment performed. Tang showed white spots 2 weeks after going to display tank. I must say white spots looked very much as ich/velvet, they started in a pectoral fin (about 2 spots) then others have appeared in the body, they really did not look as subtract or other things (almost sure). Regarding copper meds i only have copper sulphate not cupramine. Is it as safe and has the same efficacy as cupramine ? Also i cant find copper test from seachem. so, if i use cupramine (i can buy it) is it ok to test copper with salifert tests (the only one i found available).

Thanks very much:thumbsup:

I doubt this is velvet; velvet is so quick & contagious that i doubt anything would still be around. Google marine velvet and notice the coating or sheen that velvet infected fish get. Salifert test kits work well with Cupramine. Here's some good info on Cupramine, check the FAQ:http://www.seachem.com/Products/product_pages/Cupramine.html.
