Help! Guppy bullying for no apparent reason?

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!

hi and welcome aboard. :D
would you be kind enough to post as much info as
possible about the tank,
amonia,nitrate,nitrite,water change frequacy(sp),size of tank.
you have had guppys before,so i'm presuming you know
if you have males or females,please could you say
what they are.
if they are all males,then i would say maybe it's a case
of mature guppys doing what they do,pick at eachother
when there are no females,however it is possible
that the other guppy has something wrong with it and that
is why the others are picking on it.

Hi :)

I have them in a 2.5 gallon (I know, technically too small for them, but they've gotten along fine for approx. 3 months now), and all the water levels check out. I did almost a 50% change a week ago, and I kept the old filter in for now just to help with the change.

And yes, all males, and at least up until now I've seen nothing between them; no fin nipping, etc.

I kept the blue guppy separated from them in another tank all day, and I just added him back in about an hour ago. He's back to stalking the biggest lyre-tail, and he's even going after the other one as well now.

I think I'm just going to put him into another tank altogether and leave the two lyre-tail and oto cat to live happily in this one. :/ I wish I knew what was up, it's frustrating to see this happen.

It sounds like he is trying to mate with your other male fish. Guppies are very horny creatures and will try to mate with anything that moves.

hi
yes it sounds like a mature male,
i would then in that case remove him,he will continue
to carry on this way,and you will end up with your males
having shredded fins,if there is damage to the fins of the others
you can always give some "melafix" which will help
repair any damage,and hopefully stop any secondary infections
getting in.
males are rather rampant and so it is suggested to add more
females than males.
good luck. :)

Thanks, guys. I added some Melafix last night (noticed fin damage that wasn't there before) and the blue one is going to another tank in about an hour, lol.

hi
no problem,glad to be able to help.
you may still find that the other males will pick at eachother,
i was told of this by another member,and they were right.,
it didn't take long before one took over from the other.
keep the melafix on hand,as a tank of males you'll
need it.

Oh, what a wonder Melafix is, lol.

I ended up adding a sunburst way platy and another oto cat in with my banished blue guppy ... and I'll be damned if that crazy fish didn't start going after the platy within 24 hours. I ended up moving the two lyre-tails in with the platy, and putting the blue guppy in a tank on his own.

*sigh* So far, all's calm on the fishy front, lol. Gotta love learning about fish behavior!
