Copy that. Make sure the fish don't have sex. Make sure they cover up their bare body. Make sure they don't sell advertising space on their fins on eBay because someone with malicious intent might buy etc. You can't advertise fish drugs either, that would be pharma. And don't gamble on putting too many fish in too early before the water has cycled properly; that'd be gambling. Don't get fish from bad neighbourhoods. Don't listen to me.
