Hello ,brian aka grandad here. I have a problem with my clownwrasse, hes stopped eating, Ive had him about 18 months as an adult ,hes always fed well, but for the last five days hasn,t ate a thing and spends all day at the bottom of the tank. his breathing is normal no marks or disease evident seems quite alert , but is totally ignoring food , when he decides to move swims normally but not very far then settles back to the bottom of the tank.I havn,t got a clue how old he is so do you think it might be old age and hes just given up .Look forward to seeing your comments . BRIAN .
