Yeah I’ve basically figured it’ll likely grow to 11-12” or so, around 30 cm, but it’s technically possible for it to be larger. The tank it’s in can handle 11” considering it’s more eel-like in shape but if I need to upgrade that’s just an excuse to buy a bigger tank which I’ve already been looking at haha.Ive read on aquariumglaser they get to around 30cm usually in aquariums but could grow twice that size. I trust their info more than most websites but im no expert by far (im only in the hobby for about a year)
