thanks for the reply. The only thing I havn't tried is the garlic thing. I will give that a go later today. The tank has been going for a month and a half now. Recent test was a few days ago with ammonia and nitrites on 0. Nitrates only just detectable.
Once the tank was cycled I hit it pretty hard with a about 3 20% water changes with 10 days to drop the nitrates right down before adding the clowns.
Yes, the clowns are wild caught ones and no I didnt see the pet shop owners feed them
I have a pretty good relationship with one of the guys who work there and he has been very helpfull with suggestions but I'm running out of options.
Another thing that bothers me is un-eaten food in the tank from trying to get them to eat. I've tried brine shrimp, mysis shrimp, pellets, fresh fish, scollops, fresh prawn. I've seen one of them peck at the prawn once but that was it.
I guess I'll just give the tank a good clean today, change some water and try the garlic later this afternoon.
Thanks for the help
