Still not entirely convinced it's parasitic but I would definately be prepared. Blemish marks can often appear on the fins and have no relation to health. In general terms they are more akin to bruising. Parasites do tend to show up better in lower light conditions though. The fish needs to stay in the QT
for a good 4 weeks so you have time to make an informed decision. By the looks of it, velvet can be ruled out for now and C. irritans
will not kill the fish unless heavily infested to the point bacterial infections set in or the gills become affected. If C. irritans
, the spots will leave the fish when they need to encyst and multiply. If they return, it's definately C. irritans
and treatment should begin. As long as the water parameters in the QT
are good, the fish will not really be harmed by waiting.
Should I watch him for a few more days before I react with hyposalinity or medications? Hyposalinity is good for ich, does it work on anything else? If I needed to treat, would the copper stuff from Seachem be a better all around cure?
Cupramine is definately a better all 'round treatment when dealing with protozoan parasites (main exception being Brooklynella hostilis
) but I would not suggest any treatment take place prophylacticly. Hyposalinity is still a better treatment in terms of C. irritans
as it tends to be the least stressful on the fish when performed properly. There are other types of parasitic aflictions that hypo will not hinder in the least.
