My 1st mistake was buying 2 channel cats from Wal-mart,that aside since i have owned them(2 weeks) they have scratched(flashed) constantly,i have done 3-50% water changes(along with a couple 25% w.c.'s).I have tried "Ich Away" from Wardly,my ph is 7.0 my amonia is at.0.can someone give me some advice??They eat very well and always have a huge belly,really besides the flashing they seem pretty normal.
