I couldnt tell, but when I tossed it into the garbage can it fell apart so maybe it was a molt. I usually have at least one molt going on every week as I have so many shrimp and crabs. Plus i just did a water change and they always molt right after one for some reason, I guess it's the added elements.
So, is an eel a good idea? I;m seriously thinking about gettingone for the 90g. But I also would like some other cool things and not sure whats compatible. LOL I'll take those questiosn to my thread later, sorry for hogging yours.
