They're not catfish, and hopefully this is the proper forum, but I wanted to share and thought this was the place where the news would be best apperciated. Anyway, I bought a group of 8 young rhinogobius wui a month ago and just now found some eggs on the glass and a very angry father defending them. They've been free-feeding on blackworms for a month since some of the girls arrived fairly thin, and apparently it was good for them. They're supposedly cave spawners, but mine deposited their eggs on the front and side glass. I have 8 fish total and, I think, 3 males in a 10g tank. I didn't expect them to spawn so soon, but I have a 20g ready. The eggs are white, about 2mm in size, and held to the glass by a thin thread. The tank is kept at 73 degrees, rises to 76 during the day, and then drops back overnight.
I'm moving 1000 miles (Michigan to north Dakota) in two weeks, so it's too late to raise the babies before I move, but at least I know they're breedable for when I get settled in ND. Here are a few pics:

The spawning tank (yes, that's a betta in there - he's recovering from a spat with a sumo loach in another tank....I didn't expect this to be a breeding tank, but he hasn't shown any interest in the eggs yet.)

But, I couldn't raise the babies anyway with my impending move, so it's OK.
