So... these levels have been the same for about 2 weeks now-ammonia0ppm
nitrite in between 0 & 0.025ppm
ph 7.2
But i now have reason to believe that water quality isnt the problem as today when i fed shrimp pellets to another tank with 4 black widows, one of the larger black widows got one stuck in its mouth for about 2minutes and now its jaw is bent out on one side and its gills looks very similar to the other ones.
