Been keeping fresh water tropicals for 40 years now. Got interested when seeing my brother-in-laws 10 gallon algea colored tank 45 years ago! Over the years have kept mostly swords (love the shape/colors), platy's (color), mollies, particularly the lyre tails, various tetra's, various gourami's, angles (my first cichlids), cory's, pleco's (to harvest the algae). These were all community tanks in the 10 gallon to 30 gallon range. My aquariast son, working for a company called Wet Pets locally decided to redo my 30 gallon tank to brackish so now I had scats and mono's too. Did try a festivum once - got returned to LFS quickly as it was not a good community fish (LOL). A few years ago I got interested in moving to more cichlids and decided on trying krebensis and rams. I happened to be at Congressional Aquarium and was introduced to CCA. I had also increased tank size to a 45 and 55. The 45 is my lower pH tank with krebensis and rams - gotta love their personalities and parental skills. The 55 that had housed the brackish fish had been converted to my higher pH mbuna tank. Love their colors and personalities. Both are display tanks in my family room, so I get to hang with them alot. I love it when they breed and raise their fry. In fact, got a family of krebensis pulcher going now, and in my 55, have had my yellow labs and rusties holding. There is a single juvi lab living in the rock pile, and a single rustie juvie living in the holey rock.
While saltwater fauna are beautiful, the upkeep required is beyond my desire.
