One of my Cardinal Tetras has always been a little fuller in the belly than the others its blue stripe bends upwards. I've attached a (bad) pic below. I had assumed that this individual is a female and that it may be gravid. This morning, I noticed that it was breathing rather rapidly (about 4 mouth-openings per second). However, there do not appear to be any other problems with this fish or any of my others. This individual Cardinal occasionally hangs out in my bogwood "cave" but mostly schools with the others. I tested my ammonia and nitrites earlier this morning and both were zero. I can't tell if this fish is ill or if it may be getting ready to spawn.
I've had these Cardinals for about three weeks now. I recently treated the tank with Furan-2 to address what appeared to be columnaris in one of my Rummys and did numerous 20-25% water changes during this time. (My sick fish didn't respond after five days, so I euthanized it.)
My tank is a 29 gallon and was cycled about 6 weeks ago. Other inhabitants include Rummynose Tetras (7), Black Neons (7), more Cardinals (7), Sterbai Corys (4), and Assassin Snails (2). The tank is moderately planted.
Parameters:
77 deg F
pH 7.3-7.4
GH: 3 deg
KH: 2.5 deg (pH is still steady)
Nirates: ~7-13 ppm (currently 5 ppm)
Ammonia/nitrites: 0
Lighting: 17 watt T8
Any idea what's going on here?
