rosco Posted January 1, 2004 Share Posted January 1, 2004 Hi, I what to add some PVC pipe to my tank to encourage my BN to breed. What width is too small? I was going to use 32mm as I have a heap lying around but I was a little concerned about some of my fish trying to use it and getting stuck inside. Should I be worried about it? cheers PR Link to comment Share on other sites More sharing options...
fishly Posted January 1, 2004 Share Posted January 1, 2004 I don't think you should worry about it. 32mm is large enough. Regards, Fishly Link to comment Share on other sites More sharing options...
