i'd say rapheal or pictus then you have to be carefull of the rapheal they can and will if allowed to over eat and can have wieght proublems or in extreme cases rupture there stomachs because if it smells good (which is just about every thing) they will try to eat it no matter the size also they are not aggressive at all look kind of cool and can only eat fry and do a very good job cleaning the bottem floor and if theres not enough food they will sometimes come to the surface to eat
i didn't know that i thought that kribs needed ph for 7-8 and rams a apistos need water around 6.5-5.5 but i've only kept the rams and apistos
