joeyttk Posted December 13, 2004 Share Posted December 13, 2004 (edited) Hi, I have a 5x3x2 ft tank and it contains 1 blue tang, 1 clown fish and 1 green chromis. They have being leaving in harmony for 1 year plus now. However, recently, I saw my tang getting thinner and doesn't eat as much. its scales are also 'whitening' [see attached picture]. It seems like white spot [i.e. same illness as plain water fish ?] Please advise on what to do ? My tank has a few corals and I am fighting a battle with No3- recently. Not winning but not losing any more ground either. Could it be nitrate ? if so, my clown and chromis are still happily swimming and eating well. help! help! help! joey.

weileong Posted December 13, 2004 Share Posted December 13, 2004 Doesn't look like whitespot. Seems like malnutrition. What have you been feeding your blue tang? Quote Weileong's 4ft tank Part I Weileong's 4ft tank Part II Link to comment Share on other sites More sharing options...
SRC Member damien Posted December 13, 2004 SRC Member Share Posted December 13, 2004 Sypmton: not feeding. Possible disease: microsporidian infection, TB/wasting disease, vibriosis, poisoning Quote Link to comment Share on other sites More sharing options...

joeyttk Posted December 13, 2004 Author Share Posted December 13, 2004 Ya. something being wrong for a some time. http://www.sgreefclub.com/forum/index.php?...ndpost&p=318356 The tank is 13th month old and so is the tang in my tank [quite a tongue twister ] I think I overloaded the coral and after a gaint clam died on me in the 9th month [and did not realized after 4 days], my corals and fish starts to die one after another. had already done 1/3 water change 2 weeks ago and today the no3- is still between 25-50. I think I will change 1/3 [i.e. 0.333 * 800 L] again this weekend and hopefully try to catch and isolate the blue tang Quote Link to comment Share on other sites More sharing options...
SRC Member Clownfish Posted December 13, 2004 SRC Member Share Posted December 13, 2004 in ur "battle against nitrate" wat hav u done to ur wateer? wat did u add exactly? did u overdose? i dun advise u to add anymore stuffs, if so many of ur corals n fishes die, it probably means some water parameter imbalance already.... u shld hav done an emrgency water change when u realise ur giant clam died, ammonia cld hav costs ur LS... pls test ur ammonia, nitrite levels, make sure they r at 0 check for any foreign substances in ur water that cld cause ur water imbalance.. wat filter medium u using? brand + type?
