Grosvenor Tropicals fully endorsees the OATA's policy on the humane  treatment of livestock. We may refuse any sale where we believe that a customer cannot provide a suitable environment for care of that species.

We do not supply Goldfish for use as prizes at Fetes, Fun Fairs or other events.

Thinking about Marines

As I have already noted Marine Fishkeeping is now one of the fastest growing sections of the hobby, not only Tropical fishkeepers moving over, but even total beginners buying their first tank, something which would have been unthinkable only a few years ago.

With this in mind I will mention the most common question from new potential marine keepers: "Are they difficult to keep and do they require much work?"

The answer however is not quite so simple. The amount of work involved is really no more than that required to keep Tropical Fish properly, and difficulty depends upon one's experience and abilities as a fishkeeper, or perhaps I should say "Water Keeper"

Marine Aquarium

As with any type of fish keeping, it is the water quality which is the important issue. It really makes no difference if the water is fresh, brackish or salt, it has to be suitable for the fish which have to live in it.

In this respect things have never been easier, a better understanding of water chemistry and modern equipment eliminate most of the traditional problems and provide water parameters almost indistinguishable from the natural oceans. Nowadays in fact most Marine Keepers buy their Salt Water ready mixed to use straight out of the barrel.


Many of the modern aquariums come fully equipped with all the necessary bits and pieces. Marine spectrum high output T5 lighting, heaters, circulating pumps, UV sterilizer, some even include a protein skimmer.

Grosvenor Tropicals can not only supply all the equipment you will need as a 'Kit', but also deliver and set it up in your home. We even bring the salt water, Coral Sand and Live Rock to fill the aquarium and leave it running, ready for your first fish.
