Tetras stressing my angels to death?

[ibanezgfx]

about a week or 2 ago, i bought 3 neons and 3 glolight tetras. the neons dissappeared (assuming angels ate them) and the glo lights stayed. i bought 6 more glo lights and 3 days after, 1 angel and 1 ram died over night. the next night another angel died.

water tests just fine, the tank has been up and running now for 7 months with everything in it so im just assuming they stressed them out?

im left with 1 angel, 1 ram and 2 cories along with the 9 tetras

You have now learned the importance of a QT/hospital tank. More than likely the glo lights you just put in the tank had some type of disease they brought in with them. Keep an eye on the rest of your fish you may lose more.

Yeah, I agree. I always use a QT tank now. Years ago I bought a couple fish and didnt QT them. Most of my tank just up and died in a matter of days with no real signs of sickness.
