One of the finished racks will be for breeding " lil bits" aka nano fish.... The other one will be used for plant holding/ propagation, and grow out of a few species.
The 2 unfinished racks, are JUST going to be for grow outs. Seems I almost never have enough grow space !!! Surprise spawns, "volenteer fry" appear when i HAD enough space to grow everyone up... then I need another tank or 2.... So hopefully the new racks to built... will get that fixed ! :-)
Besides that and a few finishing touches with this and that... tying up the loose ends.... its ALMOST done in the room.... But I am beginning to think, it will never truly be finished ! LOL
