Shop notice
Open as usual, and not going anywhere
A note from the shop confirming that Castle Aquatics is trading as normal, with regular opening hours.
What you will find
Three reasons people come in
Stock changes week to week, so the pages below describe the kinds of things we keep rather than a fixed list. Call or send an enquiry if you are after something in particular.
Why come in
A local shop for everyday fishkeeping
Castle Aquatics was established in 1996, which makes 30 years as Eltham's local aquarium and pond specialist. Tell us about your tank, the fish you already keep and what you would like to do next. A useful conversation can help you find the right starting point and explore what is available in the shop.
Ask a real person
Describe your tank and what you would like to keep. A short conversation usually gets you further than an hour of searching.
See the fish in store
Rows of tanks you can walk along and look at properly before you decide anything.
Find everyday supplies
Food, treatments, filter media and the small replacement parts that keep a setup running.
Installation and cleaning on request
Aquarium and pond installation, tank and pond cleaning and regular maintenance can all be arranged on request. Tell us about the job and we will take it from there.
In the shop
Have a look along the tanks
A look around the shop, recent arrivals and seasonal updates. Stock changes, so please check before making a special trip.
If there is something you have been hunting for, send us the name and we will tell you honestly whether we have it, when we might, or where you would be better off looking.
Mailing list
Be first through the door
The good stuff does not hang about. Axolotls, shrimp, fancy goldfish and the odd thing we only get once go within days, and the people who hear first are usually the people who get them.
- Only the things you tick, nothing else
- A message when it lands, not a weekly round up
- By email or WhatsApp, whichever suits you
Starting out
Start with a conversation about your tank
Let us know the space you have, what you would like to keep and the equipment you already own. Ask about the options available for your setup.
Gift vouchers & saver card
Stuck for what to get them?
Gift vouchers are available in the shop. A good answer for the fishkeeper who already has three tanks and is eyeing up a fourth, and a safer one than guessing which fish they want.
Pop in and we will sort one out. Vouchers are bought and spent in store, so ask at the counter for the amounts we have and how long they run.
Regulars collect on the saver card too: a stamp for every complete £10 spent, and ten stamps take £5 off. Ask for a card at the counter.
