OK, I have been away for awhile, no excuses just here and there, So I am still fighting Ich / Velvet or something in my Salt Water tank. Done that been there with all the treatments and ideas. My question comes down to this,. So if the Ich and Velvet have life cycles and without fish they die off, one would think if I had 4 healthy fish for 2 months that the tank would be parasite free. Or at lease I would think that. So, is my thinking correct ? Well, i have my 4 original fish, Snowflake, Flame Angel, Blenny, Banded Shrimp and they have been fine through all treatments and ect. Any new fish added, LFS or mail order all are sure to die within 2 weeks with what appeard to be ick/velvet. Aside from starting over, any fancy ideas for me ? Or should I just stick with the original gang of fish that seem to be immune to this.. Shrug..
