My 4 yr old red VT Jerry was one of my first fish and he's been going strong for ages. But over the last month he's been slowing down, losing colour and gradually spending more time on the bottom of his tank. He doesn't care about food much anymore. I know there's nothing wrong with the water, stats are fine and Delilah shares his water (divided tank) and she's happy as ever.
He's been laying on the gravel all day and he's starting to gasp. Aw, I know he's old but I don't want to lose him..
