So, the rescued fish seem to be doing great, all eating like crazy. Even the neon tetra is eating dependably, though s/he's very shy; I manage to get it to eat best by overfeeding, so there's a rain of food; if I feed more moderately then the other fish seem to get it all way before it comes anywhere near the neon. Hopefully it will become stronger & braver soon, meanwhile I'm vacuuming & changing the water weekly. I'm really amazed that none of them have died yet; they all seem visibly improved, just in this short time. So here are some pictures, taken right after I got them. The neon has a slightly rounder tummy now, but is still very thin:
Here's one of the pair I'd like to identify, maybe a tetra?, with red ventral fins (can be hard to see in the photos)
It was hard to get good pictures of the rosys & minnows, they move so fast, but here's one, you can see how skinny it is:
And finally (for today!) here are the two otocincluses, alighting briefly on a little shell:
So right now there are 11 small rescued fish in the 10 gallon tank. I'm thinking of moving the two tetras and maybe some of the rosy reds/minnows to my 20 gallon tank with the big pleco, 4 mature rosys/minnows, & four 1 to 2" black & white skirt tetras. Then I'd get maybe 3 or 4 more neon tetras to hopefully cheer up the lone one. Do you think this could work?
The full-grown rosys & minnows in the 20-gallon tank seem so big & healthy now; such a far cry from what you see in the pet stores. One of the minnows has turned very dark, with vertical striped pattern (I'll put up a picture when I can). Tonight I found one of the rosys jamming its head into the gravel in the corner, I mean way past the gill-level, with its tail sticking almost straight up--it was kind of weird. I was worried that it was in trouble, so I gently dug it out with the net handle; it seemed catatonic for a minute or so, & then normal. Maybe this is something to do with preparing to breed? Another minnow went over to the same corner & poked around head down for a while too, but didn't actually get stuck or seemingly stuck, like the first. Anyway, that's the first time I've seen that behavior...
I see what you mean about hefty goldfish. Mine are about 3-1/2" & 2" right now, but they eat like mad, and now that I've raised the temp. to 70 to accomodate the ottos, they'll grow even faster. I might have to give them away to someone who has a bigger tank, though they are fine for now. I'll put up some pix of them too, next posting.
So thanks for all your helpful postings! --Karen
