I have a question for the experts, Basically where did i go wrong. I bought a coral beauty 12 weeks ago, Its been in quarantine since then at my friends house for the 1st 4 weeks then 8 weeks at mine since, Deffo no contact with other fish at friends house, Thats fact.. Healthy lovely greedy eater of a litle fish, No probs at all. I put it in my display tank sunday and last night seen it starting to show w/s or velvet? Wasnt sure.. Got up this morning and she,s covered in spot. Still feeding, not glanging of rocks and seems to be behaving ok, Had a look round the tank and my little fireball angel is starting to show spot aswell. Shes been in the tank months with no probs.The only issues ive had is a royal gram flashing at rock, I got him out as he was marked but deffo not spot, Its damage from glancing, I had added phosguard 2 days before he started to glance and was told by lfs it may be that, I check with the seachem website and it states some fish may be hyper sensative to this product so fair enough.. Why after 12 weeks q/t would it show signs of spot after just 2 days in the tank and why would it spread to my f/ball so quickly?? I just dont get it..Should say no other fish showing signs.. Some facts. No cross contamination, diff nets used on both tanks to be honest its different everything used on both tanks and everything ro dipped before going into quarantine tank,, I even wash my hands in ro if i have to put it in the tank. Any Ideas where i could have messed up??Oh Finally, Please dont say get them out the tank because now there in its mission impossible. It would stress the other fish way to much and there are to many places to hide that i physically just cannot get to.. The only fish i can get out is my royal because he is to stubborn to get out of the way of the net.. He aint to sharp btw..
