Brian,
I posted some questions about the Catfish on the
NANFA site. (thank you for turning me on to that organization) Go to the Catfishes forum. BTW, I'm starting to see a little more of the Cat here lately. He's not hiding out quite so much.
The Bluegills don't really mess with the Crays, maybe because the Crays are as big as they are, almost. The Blues do come in and steal food though. They are not afraid at all of the Crays. The 100 gallon? I picked it up for $159, brand new. 60" long x 24" high x 16" wide. I have two AC 110's on it, one at each end. Plumbed the pick-up tubes to the middle. I also have an AC 110 on my 40 gallon unit. After a week of adding bottled bacteria I took the media with all the good stuff from the AC 110 in my 40 and swapped it with the new media in one of the filters that my 100 is using. The 100 was finished cycling in two days. Probably because it is lightly stocked. Small spike in Nitrites in the 40, quickly went away. I check all the water parameters in all my tanks no less than every other day. 25% weekly water changes in every tank. All is good.
I need to set up a tripod and break out one of my Nikons to shoot a few photos. I have a 2' fluorescent over each tank that is labeled as a "garden or aquarium" light. Color is 2700k, I believe. Kind of an almost pinkish tone to the light. Looks great, I think.
I kept looking at your signature with the 90 gallon tank and thought about how nice it would be to have one like that. I actually upgraded not because of any water issues but because these critters just need the room. 4 Bluegill in the 100 gallon tank is almost crowded. Your signature was a bit of inspiration though...
I'll try and get some photos up soon. I don't have them decked out as attractively as some of the tanks I've seen here. They certainly won't win any contests for beauty. But the water is crystal clear and the lighting looks very cool with the lights down low. The fish are very cool too.
