Hello All. For a little context, my friend has a tank that is African-themed aquarium, 75 gallon long. He keeps 12x Congos, 3x Kribs, and 4x Synadontis Petricola, and most importantly, 1x 5in male Senegal Bichir. I have never kept a bichir before so I figured it would be best to ask here...

Is it possible to keep a healthy population of endlers with a larger fish that would eat them such as a firemouthcichlid? Say the endlers would breed as fast as the cichlids can eat them they would be able to sustain themselves?

Just sharing my Freshwater Eel      

Hi,    I was planning to buy a Freshwater Sea Turtle earlier.. It looks like this: http://3.bp.blogspot.com/_qRy7i8Xa2g4/TAumqRpst4I/AAAAAAAAOdU/pE_lKQaQst0/s1600/3.jpg   But earlier some random buyer said that his sea turtles died in two days after he bought it.. So I postponed it but still...
