i went away for the weekend. a neighbor fed the fish. last night when i got back they seemed fine, but perhaps a little unenergetic. the HOB filter was spilling over the edge, so i put a new filter next to the old one (with new carbon) to colonize the new filter. this caused a lot of debris to be shaken loose from the old filter, so there was a snow storm of gunk which cleared up again in about 20 minutes.
so, this morning, the smallest danio has a bright red blood-colored spot on his side. it's about 1/4" in diameter, and under the skin, i.e. not an open sore. he's obviously uncomfortable because he swims only in the direction of the spot (starboard). but he's still swimming, not drifting.
i was already late for work, but i did a quick 20% water change, added some salt and some quickcure. when i got to work i did a little reading and it sounds from disease database like it might be toxin poisoning. any other ideas?
i guess i just have to do massive water changes for the next few days? should i stick with the quickcure in case it's bacterial?
could my neighbor have done something accidently? (fed the fish with dirty hands?) could it have been the new filter i started? i'm also trying some philadendron in the tank (i know, not aquatic) which are supposedly poisonous to mammels, but they have been in there for months.
sorry for rambling on about a tiny little sick danio. i get this way when one of my little buggers isn't feeling well.
