I have a 2.5" belly crawler that is in a 20g for quarantine. I feel confident that I can add it to my 125 at this time but I have never used a grow out tank before and was wondering if it would make a difference in growth rate keeping thins as is. The belly crawler get flakes twice a day and freeze dried blood works once per day. I do a 25% water change every other day with a 50 wc once a week. When in the 125 feedings will be pellets 2x a day with 1 15-20% wc and 1 75% wc.
