We have recently stocked our 10gallon with the Glowlight Danios. Originally this was to be my 5year old's "pet" and has turned into my job rather quickly. I'm having trouble keeping these fish alive and fins intact.

Our tank currently consists of 5 Glowlight Danios, 5 Glowlight Tetras, and 1 Neon Tetra (there used to be more, and the one little guy has been doing rather well with the rest of the fish).

I have had our water tested several times and its always exactly where it should be. I've woken up several mornings to find fin-less fish stuck in the filter. The tank is right next to my desk and so I am constantly trying to see which fish are doing this. Is there something I should be doing that I'm not? Are these fish just not compatible? I currently have one Glowlight Danio that I hope is going to make it, since it is currently missing its caudal fin.
