But my electric blue crayfish seems to have fuzz growing on the little forks they use as they're mouth... I have two others who seem to be fine but that one has been acting a little strange lately..

Canadiancray Posted January 14, 2007 Report Share Posted January 14, 2007 (edited) Is it a Procambarus alleni???? Its prob. just external fouling. Not uncommon & not really of concern to the crayfish unless it is effecting its ability to eat. Its usually caused by excessive waste in the substrate. A good cleaning of the tank will normally fix this problem. External foulingProtozoans frequently foul the exoskeleton and gill cavity of freshwater crayfish. Severe fouling is usually associated with poor water quality, but may be due to reduced preening which occurs when animals are diseased. Fouling itself is of little consequence to the health of the crayfish unless it is so severe that it causes improper gill functioning, and it can be managed by water exchange. Valuable broodstock may be treated by bathing in formalin or another disinfectant to kill the protozoans. Common fouling protozoans of freshwater crayfish include Epistylus, Zoothamnium, Lagenophrys, Vorticella and Acineta. http://us.geocities.com/crayfishdisease/pages/intro.html Edited January 14, 2007 by Canadiancray Quote Link to comment Share on other sites More sharing options...

I haven't seen him eat in almost a month I think. Doesn't mean that he hasn't eatten anything but usually he's raring to go for food. What would be used for treatment? thanks again...

Canadiancray Posted January 15, 2007 Report Share Posted January 15, 2007 Formalin works really well. If it was anywhere else on the crayfish you could scrub it off with a toothbrush but in that location that prob. won't work. Quote Link to comment Share on other sites More sharing options...
