Thanks for the feedback! He's definitely a slow eater. He just meanders around and snacks. I'm sure I'll eventually find the proper amount of BBS to make and put in the tank for a single feeding. He's so small, he won't touch frozen blood worms just yet, maybe in a couple more weeks. At any rate, I have a coarse sponge on the intake, but I can see the BBS get pulled in, and I have a coarse sponge inside the filter, too. So, maybe some BBS will pass through the system and get back into the tank. I'll experiment with a timer on the filter for a few days. I assume if I'm on a 10min ON / 50min OFF timer for a few hours a day for feeding, that will keep the sponge bacteria in good shape inside the filter. Then, I'll have it come on and run full-time through the night.
