HI all,

I need some help with two of my black neon tetras.

Info about the tank:

No major changes in 2 years.

29Gal, heavily planted tank. Water parameters have been good for the past 2 years but I've run out of test supplies except for Nitrate which was at 20-30 when I checked today and phosphate (which I don't think could contribute). Gets 25% WC every 7-14 days and all has been healthy for 2 or so years. Have even had a few baby black neons hatch and grow up.

Edit: Filters: 2 HOB, AQ50 and AQ30.

Livestock: 8 - 9 black neons, 11 Harlequin rasboras, many many shrimp (started with 10), estimated 20.

Problem: for about 2 months, one of the females has appeared very fat. I thought she had eggs but she never thinned out. I tried giving some peas here and there but she's still looking the same. She has been otherwise behaving normally, eating, swimming with the school, swimming fine. Now, a second one has just started to look the same, only the second one seems to be opening and closing her mouth a bit rapidly. Otherwise, she also seems fine, swims with the school just fine and eats energetically. Scales do not seem to be protruding off of their bodies. When I got them, they are about as long as they are now, which is a bit large for a black neon, so no idea as to age but they were probably mature when I got them 2 years ago. They get fed flakes and dried bloodworms about 3 times/week.

I included some pics. One of the pics is the 'original' and the other two are of the one who recently developed similar symptoms.

I see that it might be dropsy (but again, after 2 months and scales not sticking out), that it could be egg bound, or something else. I dunno. Looking for any ideas on how to help these little girls out. Thanks so much for your help in advance!

Best,

eisbear

see if they'll eat crushed, cooked peas?
Thanks for the Reply, gonna get some peas, the one that's been big for a while has eaten a few pieces of peas over the last month or two.

Update: the more recently affected fish seems, as of this morning, to be breathing heavier, listing a bit and is hanging out mid-tank, she might not be coming up to feed and I worry if I try peas, the other fish will steal them.

I wonder if Epsom salt bath + Hospital tank is overkill at this point (I'm not sure how contagious any cause might be) but I do have a tank that has a very weak (or gone) cycle I could set up as the hospital tank. Any other possible meds or cures to try if I go this route? I seem to have maracyn - oxy on hand but I live near a Petco. I am somewhat far from the LFS.

edit: if I move them to QT/hospital, what are the thoughts on just adding Epsom directly to the tank?

Thanks!
