Thanks a lot.
And yes that is a Haddoni. I have never had a Gig, so I can just go off of what I have read.... I think they are easier, but still can be fickle, the slightest change in flow can upset them -- and they prefer less flow then Gigs.
But, lately they seem to have issues with shipping, looking great for the first day or two, and then going down hill fast -- wide open mouth.
EDIT -- but once they are settled in, seem pretty darn bullet proof. One of mine is 9+ years old, and I have made plenty of mistakes during that time, including run ins with powerheads. Once I thought for sure the blue one was going to die after I tried to move it to another tank ---- put my finger through the oral disc, and it looked like death, but since I was around that weekend I decided to leave it in the tank. Sure glad that I did. And the darn thing spawned about 3 weeks ago.
