Dionigi, Thanks for your tips, my A.nijsseni have recovered and are now eating well. Here is what I did following your advice. I treated them with levamisole hydrochloride to try and purge any internal parasites present. I also treated with Octozin (TM) which claims to cure Hexamita. Metranizadole or any anti-biotics are not available without prescription here in the UK. Thanks for your help, let's hope they have a successful spawn soon.
