well, 2 of my 4 firebellies have inexplicably disappeared, I suspect they died and the remaining 2 ate them. SO i changed things up a bit. I did away with the reptile tetra automatic heater and I did away (temporarily, until I get screen to separate it) with the coconut fiber bedding. aaand moved them all into a 10g!!
using a duetto 50 as a filter, and a 2x 10 watt incandescent hood with screw in full spectrum florescent bulbs.
and here it is all nestled into the bookshelf I rebuilt to house this tank, and eventually my 10g betta sorority.
