Too much I think. I’d say as much as they could eat in a min about 10x a day. Next I’d soak some black worms and feed them till the cup was empty. So that could have been 3+ hours of those soaked worms. I’m wondering if it could be the length of time I fed the soaked worms. But this is the way I feed all my discus. Even when I had 2” discus. I fed till their bellies looked full and then id wait till they were lean again and feed. 2” grew big.
