Fish Swimming Really Close To Surface

[Gnatfish]

Hello

Tank size: 15 gallon
pH: 7.8
ammonia: 0
nitrite: 0
nitrate: 40mg
tank temp: 28-30

Fish Symptoms : My female Egyptian Mouthbrooder is hovering really close to the surface. Near the filter and is just staying there. She did look like she was carrying eggs a few days ago and she wasn't eating, which is what they do. But then they went and she still wasn't eating.

Volume and Frequency of water changes: 50% on Saturday

Chemical Additives or Media in your tank: None

Tank inhabitants: 5 Harlquin Rasboras, 6 Lemon Tetras, 1 male Egyptian Mouth Brooder. However they are acting fine.

Recent additions to your tank (living or decoration): The mouth brooders were added 10 days ago

Exposure to chemicals: ... none that i know off

Digital photo (include if possible):

I took this outo of focus photo

Then as i got closer to take a better photo the fish swam off

Then went back to same place

Help!

Is there enough aeration in the tank as in this weather you have to increase it, if she not eating not good, any signs of salt like spots on her, or a yellow gold dusting on on the fish, does the fish look bloated.

No signs of salt or gold dusting. But i'll keep looking out for that. Someone just mentioned to me that, she could be being bullied. The other Male does look a bit rough. If she isn't dead by the time the 10 gallon is set-up i'll move here to there.

Well, you know i said she hasn't eaten for a while...

I just fed her and turned the aeration up and she seems fine now!!!!

I'll keep an eye for her though

Ok, good luck, need alot of aeration in this weather as the high temp soon reduces 02 in the tank.
