The vet told me to leave the temperature at 68 degrees. He said instead of putting the temperature more up to quicken the life span of the parasites, to do the exact opposite. He is here now looking at Ruby and helping me with the main tank to see if anyone else has it. My citrus looks like he's about it, he didn't eat when we fed and he's a cow when it comes to food so we gave him a peroxide bath. We dosed the main tank with all the fish and coral. He said to do it every 12 hours and put the temp at 68. instead of quickening the lifespan of velvet, he wants to do the opposite; slowing it down so it can't reproduce and have a chance to get worse. He has a 250g aquarium at home; he's a exotics vet. He had to deal with this one day and he had no fish die using the peroxide if you do it very carefully. every 12 hours 4mL only since I have a 40g tank, just enough to not stress coral, but enough to kill the velvet over time. He said to do this for 30 days. I am going to do 1030am and 1030pm 4mL - a water change after 15 days. and another after the 30 is done.
Edit: I am going to work now - I have a break around 6/630. I will check on Ruby then and keep you posted how everyone and her is doing. I just can't believe this morning before I left for my first job, she was upside down a few times. I really had to encourage her to move - this is what the vet said to do. When you see them on their side or upside down, to always help encourage their mood to move and fight. When I got home from work she looked dead. After the bath - she is now swimming and not going sideways or upside down. She's still breathing very heavy but she is swimming normal. I will try to feed her when I get home. Hope she pulls through!
