I 'adopted' Toothless from an online friend who found him with fin rot so bad that it had advanced to body rot - and that's how he got his name.
Poor Toothless had done so well and grown his fins back in - then silly me tried a 55 gallon divided tank with DIY dividers that slipped. One fish single handedly killed Toothless, Rosey, and himself.
None of the fish died immediately - Rosey was bad off b/c he was a rosetail so wasn't strong enough to handle the injuries. He had scales missing along with massive fin damage. I had hoped to nurse all back to health, but the injuries were too severe. Rosey died about a week later.
Cloud (the culprit) died yesterday, and Toothless died today. About 2/3 weeks later.
RIP beautiful boys.
