Hey all -
Had a school of 6 neon tetras in my community tank - bought them about 2 weeks ago. 1 tetra died soon after purchase, didnt see it coming he just dissapeared then I found him dead in some clumps of plants. 2nd neon died, or rather was on his way and was euthanized about 5 days ago after he appeared to be having equilibrium problems and appeared in distress. So after I was down to 4 neons, I noticed that they had broken from their school and now are nipping at each other/chasing each other away. Is this due to the # of them or is this some other reason for their nipping at each other?
On a side note tonight a bleeding heart tetra in the same tank was noticed doing the same frantic swimming thing (equilibrium problems), so he has been removed and quarenteend and i am attempting a salt/melafix dose, although I am sure whatever this is has progressed too far for treatment.
I looked up neon tetra disease and I gotta say the indicators they give really are not applying to these fish - only the restlessness/difficulty swimming. No discoloration, lumps, etc. Maybe it is - i dont know. I certainly hope not for the sake of my other fish.
Any ideas about both these problems?
details for those interested:
0 nitrites/amonia, 20ppm nitrates, 77*F, ph 7.2, planted community tank with fancy guppies, blue gourami, apple snails, otocinclus, emerald cory, albino cory, neon tetras, 1 red eyed tetra (who thinks he is a guppy), and 1 ghost shrimp named Fred.
