Hey guys, came to check it out on a suggestion from another board, because I have a guppy mini-crisis going on.
I have two lyre-tailed and one regular fancy guppy, and they've co-existed nicely for a few months now. The lyre-tailed more or less buddied up, and the blue fancy chummed along sometimes.
They were fine earlier this evening when I fed them, at least I didn't notice anything then. Now, I noticed that the larger of the lyre-tailed is less active than normal (no visible signs of illness on his body anywhere) and trying to just hang around behind the plants.
However, a new development would be the other two harassing the hell out of him. They aren't truly attacking him (yet), but both (the blue more so than the other lyre-tail) are brushing against him, going snout to snout and lightly pushing him and stalking him wherever he tries to go. Constantly.
The only thing (other than lack of energy) that I see different with him is that his eyes see larger than normal. I've kept guppies several times before, and I've never seen their eyes do that.
The only thing that's changed recently was the addition of an oto cat to the group, and there have been no problems with him, nor is he joining in the gang.
I think I'm just going to try taking the blue guppy out for now, he seems to be the most agressive in the whole matter. The more I think about it, I think he may feel threatened/maybe a little aggressive because of the addition of the oto cat. The cat took a liking to him, especially the first few days, and would follow him around the tank from time to time ... maybe it freaked his little loner self out, I don't know. I'm just trying to figure this out.
Thanks for any suggestions that you can give me!
