This spawn has really caught me off guard. I struggled so much on my last two, with the setup, keeping water clean, etc.... and I thought they would die without a bubblesnest?! Ive always heard eggs will not hatch that stay at the bottom. ALL of them did. even the ones Dumbo overlooked and left under moss balls, heater, corners, etc. Just weird. I guess you cant believe everything on the internet. HOWEVER i would not advise anyone to try to breed without the male having one! and the water level is about 12inches high! should i worry about their labyrinth organ developement?? dont know if this will affect it in some way?
