Umm... one of my male guppies' tale seems to be trimmed. It's shorter than it was yesterday, but still perfectly shaped. The water is still 0,0,5, and it's been that way for over 6 weeks, since the tank cycled. If he was being nipped at by the danios, wouldn't the tail be scraggly? It's really perfectly shaped. And I haven't seen any nippiness.... :shock: help, please?
