Little fella's are still growing and doing well. They are now seeding up a new JBL401 ext filter and looks like the heavy feeding / bio load in this tank is hurting the pre filter sponges already

. 2 weeks but I guess removing the old under gravel did stir up allot of crap for it to filter out. Over 50 of the little guys still sitting in the tank am looking forward to reclaiming it one day!
For anyone interested in how they are growing slowly but still all on the grow. A few are starting to shoot up in size guess its the usual front runners in growth.
