The New King in Tom's Mbuna Aquarium Yikes !! These pictures show a beautiful young male Mbuna Cichlid, living in Tom's Mbuna Aquarium. This fish a Labeotropheus trewavasae, one of the many species of Mbuna Cichlids that live among the rocks along the shores of Lake Malawi in East Africa. This fish is now about 4" long, very lean, moving up in dominance, and increasing in color. His mouth, which you can see clearly in the picture just above, is quite different from most other Mbuna species. Tom and Nevin will probably talk about him during the next Pet Fish Talk Show. As always you are invited to call and talk about fish.     EcoBio-Blocks to the Rescue !! Here are some of Tom's Mbuna babies. They're a few weeks old and enjoying a swim through a green EcoBio-Block. This aquarium was dark green a week ago, which may have been caused by cyanobacteria. Click here to see the aquarium then. A few days ago Tom put the EcoBio-Block in the aquarium. It probably took a couple of days for the beneficial bacteria in this EcoBio-Block to become biologically active, and in a couple more days the cyanobacteria were gone, the water was clear, and Tom had a big smile. Tom and Nevin talk about this aquarium adventure during this show. EcoBio-Blocks are available from ONEdersave, which sponsors Pet Fish Talk.

Bonnie from Iowa calls and says she took all the water out of the 150-gaalon pond in her sunroom, then rinsed the pond out well, filled it with tap water, and added water conditioner. It's been a week now and the pond still has ammonia that can be measured by the test kit. What do do next? Nevin says the denitrifier, which he recently built, is just beginning to reduce the nitrate in the water in a system with 11-aquariums and about 800 to 1000-gallons of freshwater. Ronnie from Missouri calls and says he found some really nice Black Sailfin Mollies in a local store and he's going to breed them. He gives some hints about hatching and growing brine shrimp to feed to fish. Finally, Tom and Nevin offer to send him a free sample of the premium food.
