yeah i feed massivore to them. the jag is not showing any signs it's just the oscar. It turns out the "silversides" i got at my asian market are smelt. Smelt contain thiaminase and i have stopped feeding it to my fish.
The link i posted says that "silversides" are just the name of any small fish that has a lateral silver-ish marking or stripe. It is not the name of 1 particular species of fish. Different fishfood producers use different species and sell them under the umbrella-term "silversides". According to the author of the material in my posted link, the best brand is SF Bay/ Sally's Silversides. This company uses Menidia Menidia species of silversides which do not contain thaiminase and are NOT smelt. To confirm this, I have emailed SF Bay last saturday and asked again what species of fish they use. I am waiting for their response. In the meantime I have stopped feeding frozen fish to my cichlids.
I like the material in the link i posted....problem is that 1) i don't know how credible the authors are. 2) it was written with reptiles in mind. A lot of people like feeding fish to their garter snakes. 3) there's not a lot of info out their to back any of this up.
So for now, i gotta go with it. I dunno why my oscar is getting HTH....water quality is good, no carbon in my filter, etc. I gotta this theory a shot and see what happens.
There is also a sticky in the forum Fish Disease and Illness posted by Miles, he says that after a lot of research he thinks thiaminase is to blame.
