A Suitable Replacement For The Shark?

I think Colin's post was a bit tongue-in-cheek Cazzy - you'll find that most regular forum users on here have a tendency towards daftness (apart from me of course - all my posts are deadly serious  ) but there's usually a dollop of good advice in the mix! 

Cazzy, dbag is quite right, some forum users on here can be extremely juvenile I do try to keep them in check but they are boys after all, and even my level-headed, serious approach to the forum doesn't always keep control of them
We are a friendly lot really and are used to having banter amongst ourselves, but perhaps our humour is an acquired taste, and we should restrict it to those that are happy to join in. I, for one, will remember that.
We'll have to ask Robert for a tick yes/no box to banter, sarcasm or ribbing on the new membership page

Having said all that, Colin did go to the trouble of finding some fish choices for you to look at, so a thank you might have been nice.

Thanks dbaggie I already have some mollies , they like going through the gravel but don't really give the deep clean the the shark would do to plants and ornaments. Any how I will leave this now as I feel I'm in the wrong place.
