Are you keeping them with other fish? i suggest not to. I had a pair of bolivian rams and they becam extremely agressive. attacking almost anything in my tank, they shredded my bettas fins, almost killed my corys, even tried chasing my tetras. they are not community fish so you need to keep them with other boisterous and rough fish. Other than that they are pretty easy to keep. They're not hard to feed, and I never had problems with them being sensitive to ph or akilinity. Put a cave and lots of plants in the tank fr them, they like the securtiy of a cave to hide in when it gets dark. Hope this helps! They are nice, but really aggresive and i ussually don't recomend them because of that, but everyone has their favorite fish! Just make sure not to keep them with timid or easygoing fish and you'll be fine!
