####, i do have other fish tanks other than a 55 litre tankhumm.huh, i am not a beginner just because i have only just joined this tropical fish forum, i have had other tropical fish such as oscars, eels, Purana'slol, a beginner starting with malawi cichlids i bet he hasnt even a clue about Ph. If its 55 gal then yes ok, providing you know the requirements of these fish and that you will find it hard to control aggression, they require a huge filter in order to add more fish to balance out the aggressive attitude![]()
