Aquarium capacity

Question
I have a 75 gallon freshwater tank with a Fluval305 canister filter. I am putting in one male and two female Cichlids from 5 different genuses (all peaceful)for a total of 15 individual fish. My question is, can I put in more Cichlids or is this a good amount?

Answer
Hi Pyntail,
Thank you for your question. Sounds like you are taking on an ambitious project. Sounds okay to me. This is the type of quesiton that you can ask the sales people at your local aquarium supply shop. They are the experts.
I recommend that you read and print my guide to holistic aquarium care. It might save you some time and energy:
