The tank's been cycled for about a month now. I think it may have just been stress. I'll post parameters once I've had a chance to test them all, it will take a while.
And I'm getting the last one today!

Not sure what kind it will be, I thought the lfs guy would just get me a marbled one, but today I called and he said they had just gotten some new angels (they get theirs from some local breeders) and I could come by and get one. So still probably marble, but maybe black or natural or whatever they have.
I have a question: Will farlowella catfish eat fish eggs? They look cool and I'd like to keep one or two in the tank with my angels, but if they eat eggs, I guess I can't do that.
BTW, the lfs that sells them says they grow to be 7 inches or less. Is that right?
