Fish hangs out near the water surface

[FishyTT]

I just finished cycling my tank (72 g) using fishless cycling method. It took me 5 weeks but finally the tank cycled on last weekend.

I just put in 15 platies and they're very active and fine. However, one of the platy spends most of her time near the water surface while the rest of the platies stay aroung the middle of the tank.

Has she developed any problems?

I keep the water surface moving constantly, so I don't think I have any oxygen problem. I test the water and the parameters are good:

0 Ammonia
0 Nitrite
5 Nitrate
Ph 8.0

I'm new to this hobby. Please help.

Thank you so much in advance.

I have a 15gal with 6 platys and two of them occasionally hang near the surface. I've had them for a couple months and they seem perfectly healthy.

It's only the females that do this (I have 4 females and 2 males). I've thought they may be hiding from the rather amorous males. What is your male to female ratio? You should aim for 2 to 3 females per 1 male otherwise your females can be stressed by the males, who think about 2 things, eating and breeding (kinda like human males!) :D

As long as they are not gasphng (ig. sticking their mouths above the water, breathing fast) it should be fine. Mine do the same thing at exactly 4:00pm when I get home and feed them. Just check your water levels, maybe do a 25% water change and they should be ok.
