My red seemed to grow a bit and be generally happier after a kill. Could be a relation.No I don’t have them. When I get the manueli in the 180 I’ll have an empty 65 for the convicts . Once they start breeding I’d use the offspring as a food source for my manueli. He’s currently on a diet of mainly talapia soaked in vitchem with the odd piece of shrimp thrown into the mix. I recently had a few tetras in his tank, he picked them off one by one over a few days. it seemed like his colour popped and having live food in his tank he was much more active. Noticing that now has me thinking about breeding a food source for him. I don’t necessarily care about feeding live but if it has benefits for him why not. I would continue to feed talapia/shrimp with a couple convicts a month. I wonder if anybody has tried this and noticed and difference when adding a live food source plus filets/shrimp vs frozen filets.
