Hi everryone, I want to do a group of 3 - 4 (1 male 2 to 3 females) German rams, and maybe some Cories and hatchet fish in a 20 gallon. For filtration I have a aqua tech 30 - 60 gallon filter with a bag of chemi-pure elite in it. I'm wondering if this is overstocking since my tank is a 20 gallon high. My tank also has a Ph of 8.2. Will these fish be health and happy with the Ph so high? I've heard if you acclimate Rams slowly they'll be fine, but I'm not to sure.
