Testimonials

Was down there recently having problems with my marine tank. And kit down there was great help and full of information. Thanks!
Stephen Flanagan
I think this is a great site for buying fish products as its way cheaper than my local pet shops for things. Just great.
Jackie Hind
Very happy with the service guys, had no idea about what I needed but you made it very simple without making me feel like an idiot!
Neill Austin
Have to say your shop is great and really pushing the hobby in Ireland forward with your enthusiasm. Second, to none, that's for sure.
