So have had this young fella for bout 2 1/2 months he’s about 6-7in, tank is a 30g / 110L growout. He was in with a Pantadon Butterfly for the whole time until it jumped out from an incorrectly fixed lid. Was eating well, would follow my fingers around and ate garden worms voraciously. Since the Butterfly decided to leave, he’s been really shy, and not really eating that much. Wondering if it’s because the Butterfly was a bit like a dither fish, made him feel secure? Have no clue! Also removed a floating mat of ambulia which would have diffused light. Just worried if it’s a more serious disease or something, any suggestions would be appreciated! Cheers
