Derek,
I like your RDF, it has a little offset, but it should work well. After you have fish in the system, let us know how it does with the offset.
If the offset proves to be an issue, it shouldn't be too hard to correct it. I built the RDF using spare fittings and pipe lengths I had on hand, but I might modify it a little bit to make it a bit more permanent.
I've had slightly over 1 year old bluegill spawn. Granted they were fast growers at about 6 inches.
I have 4 to 7 inch bluegills in an indoor tank that won't be a year old until June or July.
Do you spawn your bluegill in tanks, or do you stock them into a pond to spawn, and then seine out the yoy?
