My condolences first of all, I had just lost two of three of my recently acquired Rams. The third seems to be fine and quite active. He has 11 Flame Tetras for company in a 33 gal tank and I was wondering, should I get some tank mates of his own kind? It distresses me so because his 'girlfriend', the healthiest eater of the bunch, has sadly departed as well. My pH had dropped to 5.5, the embarrassment, might this have caused their unfortunate demise? Winston
