Yesterday I discovered that the Sailfin Molly had gone to the big fish tank in the sky. Over the last week his swimming had been getting worse and we noticed that his body was starting to bend. I think he might have been suffering from old age and like humans who become hunch backed, so do fish. I have noticed this with a few fish that I have had.
An interesting thing I have noticed about the tank is that the female fish live longer than males. Most of the deaths we have had were males, not sure why that is. Could be that the males were older when we got them or that they have short live spans. Or by going on the number of baby Mollies we have, they just wear themselves out.
