Yes, Rams are only one type out of hundreds, theres peacocks, dwarfs, zebras and ect., But depending on the type, most of them get big enough to eat a full grown betta.
so....no one ever really confirmed my question about if I even have enough space for another tankmate? Also, I have read that certain cichlids require different pH levels? How will that affect conditions?
I only got one. I noticed that Dovahkiin is starting to get a jealousy streak. He gets testy with Skitters (my cichlid) if I don't come home at an early enough time to sit by the tank for at least an hour and spend quality time with him. He doesn't do it on nights when I don't have my night class. For this reason (among others), I'd totally just stick with one until you know how your betta will react.
