Im thinking of adding a pair of blue rams in my 36G. PH 7.4, Amm and nitrite at 0, nitrate 10 to 20ppm and gh 6. I do twice a week 30% wc (10 gallons) and test 3X a week. Currently there are harlequin rasboras, neon tetras and panda cories. All fishes are well and eats well. Im carefull of not overfeeding. Well, most info i read from rams are mostly experts only fish. What makes this fish for experts only?
