Alright, I own three platies. Two are sunburst platies while the other one I have no idea what she is. She's black with a yellow line that runs through the underside of her body. Anyhow, my black platy is as happy as she can be... non-stop eating. I have been waiting a while before moving all three of them into the newer bigger tank.

The problem however is with my two sunburst platies. They have both grown extremely timid, hiding in the back bottom left hand corner of the tank. One of them is barely eating. His tailfin has been shredding a little but I know it's not tailrot... I know what that looks like. There is no fungus anywhere, no signs of ich, no signs of anything externally actually except for the tailfin. However, the other sunburst is fine but still as timid as the other. I thought perhaps it was a temperature thing, so I lowered it a little as I know platies tend to prefer mid 70s degrees. I used the recommended dosage of meracyn 2 just because it was recommended for fish that are not eating even though they show no signs of disease. I have been seeing him eat a little more now and his tail is getting better, but the fact that both of them continue to just stay hidden away in that corner worries me. Are they afraid of something? I'm fairly sure that my serpae tetra was the culprit of the tail problem, I've caught him harassing a little, but he has stopped doing it. Figured he had just claimed his territory and was done with it, all the way on the other side of the tank. But the tetra has never harrassed anybody else, not the other sunburst or the black platy. And he is no longer harrassing. They are the only two fish in my tank behaving this way. I also have a chinese algae eater in there, but he only chases when fish near his cave. He only comes out to eat and then goes back into hiding.

Perhaps this is just common of sunburst platies? I feel bad cuz I wanted them to like their new home. It's an incredibly heavily planted tank, could that be a bad thing? They don't have a problem swimming through the plants though. One's male and the other's female. Are they just making a home of that corner? I watch them very closely, and as I said, have not noticed any signs whatsoever of disease.

Any ideas?

Water quality is as follows:

46g tank

Amm - 0ppm
Ni - 0ppm
Na - 5ppm
PH - 6.8
KH - 3
GH - 5
DIY CO2
2 50g filters (marineland biowheel and aquaclear)
undergravel filter w/powerhead
2 5g bubble wands

Perhaps too many currents? The black platy as I said does not show this timidness. She's everywhere. Eats non-stop, but she's been that way for six months now since the first day I got her.

Any help would be appreciated.

Thanks!

Oh, and I also just changed my 30w light for a 96w compact fluorescent. Perhaps the extra light is affecting them in some way?

Okay...that's all I can think of for now.

Thanks again!

It may be the light, did they start acting odd when the light was put on the tank? When did you get your fish? Sometimes, Livebearers such as platies are of low quality and do not do well to change, such as being added to a new tank and they just perish. I would do more water changes, do them regularly as in weekly and you should notice a difference in your fish.
 
I really do think it might just be the light. I bought some lunar lights and watched them last night after lights out. They came out and where everywhere. This morning, I turned on the light, and they went back into hiding. Are platies nocturnal? Or do they just hate this bright light that much? It's so strange though that the black platy goes into hiding after lights out, and the sunburst ones come out to play. Weird...

Dats strange behaviour. My two platies school with my rainbow fishes. I did have a third one, but the same thing happened to Spot (whitish, with a black spot on its tail, but not a Micky Mouse spot). My guppies terrorized all three platies but they ripped Spot's tail to shred. I removed them and treated Spot, but I think the stress was too much and he died.

Sigh. I hate losing a pet. Any kind of pet.

I'm reading this because the same thing is happening. I just bought 3 sunburst platies. One of them is hanging out on the bottom of the tank, very timid. The other two are doing fine. I have not changed the lighting or anything else, though. And the other fish don't seem to be harrassing the new ones.

A friend said they are live-bearers, so maybe it's laying eggs, but I'm a newbie to this. Does this make sense?

While we're on it, do these fish deficate (poop) strangely? They have long, greenish 'lines' coming from their underbellies -- how come they poop like this?
