I buy my fly media from Black Jungle and my last cultures ended up moldy. I made them by mixing equal parts of the media and water and then sprinkling yeast and fish flakes over the surface.
When I saw those were going moldy, I noticed there were new instructions on the package that said you should mix the yeast with warm water and then evenly disperse it over the surface. I did this for my next batch, and this morning it appears that there's a bit of mold in them, too.
What should I do? Has anybody else had problems with Black Jungle's media? I re-use my old deli cups (although not the ones from the moldy cultures) could that be a part of the problem? Is it the fish flakes? Should I mix a tad of vinegar to the media, even though it only specifies water?
Also, since my last few batches are ruined, I've really been skimping on the feedings and I'm worried about my frogs. Hopefully I'll get to a pet store today, but if it happens again, can I collect insects for them (ants and stuff)?
