Yeah, the little guy is eating pretty well. Not gorging, but eating at least a few pellets each night. I usually keep some feeders swimming around as well, just because I want to make sure he's eating.
In regards to the sen, that is my first monster ever: Dinky. I bought him in college and he's moved into 3 different apartments, 2 different states, and now that we have a home, 3 different aquariums..... He does look a little fat in that pic though.... And in real life for that matter.
Minor update: these are the best pics my phone can manage. Just sharing a bit of Sir Vivors progress. Still happily eating floating carnivore sticks. When he gets bigger, I hope to get him on shrimp and tilapia.
