Rock kribensis. Can be gold silver black etc. it is part of the cichlid family.
Size: Males-5 inches, Females-3.5 inches.
Sexual Maturity: .75 inches
Sexual Dimorphism: Males are larger than females, and are a lot more colorful than the females which are brownish-gray.
Small Rock Kribs can easily be kept and bred in a 10 gallon tank with some rocks. As they get larger a 20-40 would be suitable. I recommend putting them with Malawians and Central and South Americans because they are good dither fish, and although they aren’t aggressive, can easily defend themselves.
