I had mine for 2 years and it went from about 2 inches to 8 inches in that time. It was just costing me too much to feed and run a 75 for one fish. I don’t think he was cramped yet but he was definitely bored. He destroyed his tank everyday.
He went into a 2000G tank at the aquarium on the boardwalk. I’m not sure how long they kept him since the head biologist got transferred to a “real aquarium”.
I ran a wet/dry with a 15W UV. I changed 20% every 2 weeks. Heater was in the sump and no power heads in the tank. I have had a few customers tell me about them breaking heaters and even bighting the cords
And yes I too have been bitten my fish. He was afraid of nothing so I had to use a scrubber in a stick.
With all these bad points I would do it again. A great pet IMO.
If you can try to get one from the Red Sea. They are more colorful. With more orange in them.
