i'm trying to feed mine lightly because i have to go on a few holidays to mauritius, india, rome and france and i will be away for at least a month. currently i am trying to "train" my mum on how to feed the fish in my room, she looks after our bala shark in the kitchen, but she overfeeds him and he is an absolute monster! but i know i won't be ableto do a water change for at least three weeks when i go away first so i am trying to get her to feed lightly whilst i am away.i put in a piece of prawn in his tank today, and he loved it! he came swimming out and nipped it a few times, then started doing a weird swim, then eating a few bits, swimming here and there, but now i'm at my desk he's gone back into his cave with his head popping out!
