Many species of fish will lie dormant at night and their color will fade. It's a natural response to lack of light usually. It may look worse than normal due to the ailment the fish has.leesanhua said:ok... i treat my clown with RID*ICH by kordon brand. it was ok last time, i put the medi by following the instruction. this morning when i woke up, i was freak out. the color of the fish almost fade out and one of them was lying on the ground and breathe heavily. as i know when fish has that behavior.
Rid Ich is not going to help you much but as far as the salinity goes, maintain it as normal. It does not need to be manipulated for this treatment. So far from what I'm hearing, the clown may or may not have ick but the signs are pointing towards something else as well. Do a google search for Brooklynella hostilis.one more Q, when i give then treatment. what is the salinity should i keep?
