Last 2 weeks, we ran out of black worms (supplier didn't get them) and we had no choice but to switch to frozen blood worms. Anyway, the juvies were quite puzzled to see the frozen worms not moving about, hence didn't take the food in the first feeding.
Now that they've gotten used for a whole 2 weeks with frozen worms, interesting things started to came about.
With fresh black worms, they always have huge full belly. With frozen, it never be the case. They only eat when necessary and then stop altogether, ignoring the food. Hence they never get full belly.
Well, that's not the problem. Moving onto day 4 of frozen worms, we started to notice that a few (four or so) of the juvies didn't want to eat...then they got dropsy.
Once they've got dropsy, that's it....no way to safe them if it's too late.
Food related dropsy sometimes quite easy to solve, just have to starve them a couple of days.
Anyway, the interesting part is to see switching to frozen food can cause dropsy. I think it has to do with bloating effect caused by frozen food.
Now that we've got life black worm stock, all is great. No more dropsy, all juvies had fat big belly, and they're a lot more active!
