whats cynobacyeria? and i dont mind hands in my warm breeding tanks, but my chilly 78 degree tanks i avoid :P
Blue Green Algae, thoguh it really isnt algae. Pesky bugger that killed off all my horn wort and have blanketed my tank over ngiht a few times. trying to keep it under control by takign ti out as i see it lol
I use silicone "pinch cups" or silicone kiddie cups as betta caves and hidey holes.
I just cut holes in the cups or mini bowls for them to swim through, stick the cup upside down, and if needed stick a rock on top to hold it down. They love their little caves.
