So, I think ive been obsessed with the silver arowana since I first laid eyes on them. Since then ive had around 10-12 Arowanas. So far ive only had luck with one of them and it was given to me when she was already 22", very docile and let me hand feed her. Sadly, I couldn't watch her in my 220 gallon aymore, she was too big for it. So she's doing well in a friends outside pond. Since then ive tried 5 other arowanas, all of them around 12-14" I cannot get close to the tank or try to clean intakes at all or else she bolts and jumps around banging her self in the lip. Any way to stop this? or do they stop doing this once they hit adulthood. She's developing a lump on her lip from the amount of times she bang her self. Right now I have the tank in the living room so she's always watching someone. So it shouldn't be a problem of low interaction with her, I sit sometimes close to the tank slowly, and she wont freak out. But the second I stand up and get close she freaks...
