Tropical fish

Very nice set up, lovely fish. As a first time getting a tropical fish aquarium set up it was great getting plenty of information and help choosing the correct fish required for my new tank setup.

I would recommend this pump

I purchased this pump to replace a Oase AquaMax Eco Premium pump which had stopped working. It came with a nice long cable and the pump looks solidly made. I connected the pipes up connected the power and all went well. The flow of water is comparable to my previous pump, it has been running for a couple of weeks without any issue. Hopefully it will last a good many years. I would certainly recommend this pump, and would highly recommend Swallows Aquatics.
