Quite interesting, I go out of town on fridays and come back on sundays. I'm surprised they all survived. I still see 1 or 2 swimming vertically/can't swim. However, I did put like about 10ml of vinegar eel on friday night. Came back and put some more in, I also put some fine powder, supposed to be "micro", but it did attract a lot of the frys though. They started to munch on something too small for me to see. I wasn't sure if it was vinegar eels or something smaller, I was able to see some vinegar eels swimming in the area too.
My tank does have plants and small micro critters swimming around and i saw a worm, maybe detritus.
my heater and airline tube for sponge filter is starting to build a fuzzy brown coat. - what should i do?, also the bottom seems dirty, but then it could just be the IAL.
