Thanks guys. I think the misbars / flared gills etc are mostly genetic. Even in the wild there are misshapen fish. You don't see it as much because you don't get even 5% survival in the wild. We are looking at huge numbers of fish in a very tiny area. I haven't done anything to lessen it I don't think. I feed my fish well and change the water weekly / clean the tanks.

I agree FB I know I see the odd one when they are growing but by the time I sell them they seem to be fine.
Thanks Dazed. If I could change something I would have my returns moved so they aren't putting water in so close to the overflow. I was somewhat limited with the furnace ductwork in the way. Other than that I'm quite happy with my setup as it stands. I'm trying to figure out this sump though... I know I'll finish it then wish I'd done it differently.
That is an excellent point. You could start with a shorter standpipe when they are young and replace it with a longer one when you want to increase the volume of water in the tank. You also have a lot of flexibility of what you're using the tank for by not drilling the drain in the back. (which is what I was going to do)<a href=showthread.php?s=&postid=14440210#post14440210 target=_blank>Originally posted</a> by FB
Is your plumbing glued or hand tightened into the bulkhead? With an empty tank you could easily change the length of the standpipe.

I like your design even more as these subtle features are pointed out.

True! I guess "replace" should have been "extend" when the tank has fish in it. :rollface:<a href=showthread.php?s=&postid=14440334#post14440334 target=_blank>Originally posted</a> by FB
The only problem is you can't just change the standpipe with fish in it. When you pull the pipe out the water will rush out along with all the fish. However an adjustable length standpipe would work well for this. You could start with a half length pipe then snug fit a coupler and snug fit another small length pipe and this would work well to increase water depth.
