I was right, my last adult succumbed to his injuries last night. The fry are still seemingly healthy. I treated both the small tanks with copper (which killed all my anachris, didnt really want it anyway cause it would have been a weed in my new tank) and it cured the male and prevented the disease from spreading to the fry but it would appear the male was to damaged to survive. Its ashame the four of them never made it to their new home.
