Well, I was just looking at pics of shell rot online (it turns out that Joffrey doesn't have shell rot, it's just some rubbing on top of his shell from playing under the new floating log, so that's a relief)...
However, I've just discovered that what I always thought was just a variation in shell patterns on Jalapeno, is actually symptomatic of being overfed.
He has the sort of jagged fringed edges of his scutes and the little trident pattern behind his head (so it looks like there's the one prong right behind his head). He seems perfectly happy and playful otherwise, and Joffrey doesn't have the same problem at all (he looks pretty smooth actually). And it just sort of occurred to me that Jalapeno is the bigger pig of the two, even though they were hatch lings together and are currently almost the exact same size.
Any idea how I can get this situation under control? I imagine that it will take a while -- assuming of course that it's at all possible -- but I don't feed them every day anymore like I used to. They have minnows swimming around so they can hunt (the minnows have plants and places to hide so a dozen last a LOT longer than they used to before we switched to a bigger aquarium).
Any advice is appreciated. Thanks.
