1) yes i have done water test, ph is 7.0, ammonia is 0, nitrite is 0 and nitrate is about 20 ppm
2) i have added these 2 rams about a month ago, they get along fine
3) i havent notice any changes in their behavior such as itching or rubbing
4) i do a 30% water change either once or twice a week. i currently have them in a 15 x 15 x 15 cube, temp at 71
fyi, i added excel flourish recently to help my browning plants and added a spirulina pellet to their diet.
thanks for any advice you can give.
