OK so i want some opinions, i am looking to convert my tropical tank to a african cichlid tank...I know what i need to do in regards to tank setup, water quality and filtration and such, i have experiance with Discus and Angles and such, but i am going to go with African Cichlids...it seems everytime i walk into the aquarium store they are always always acitve and looking at me, while my other fish besides my clown and Khuli loaches are kind of boring....I have had standard tropivcal fish for 10 years and i want to be more interactive with my fish but i dont want to go with a salt water yet because I dont have enough room for the tank i want, so I figured going with the african cichlids is one step up from tropical fish and then the next step will be salt water... Does anybody have any additonal adivce be it, rocks, substrate, species? water changes..... anything?
