Species care guide

Fish Care Guide

Use this guide to check the aquarium size, water conditions, behaviour, compatibility and feeding needs of this fish before bringing it home.

Live fish are Click & Collect only.
Order online and collect from Newlands Aquatics.

Overview

Mahachai Siamese Fighters are Betta mahachaiensis, a distinct species associated with coastal habitats near Bangkok, Thailand. Supplied size: XL. Size at sale is not adult size.

Behaviour

A distinct wild-type betta species, not an ornamental Betta splendens variety. Males are territorial and need access to surface air.

Tank Size

We recommend a planted species aquarium of at least 60 litres, with shaded cover, gentle filtration and a secure lid above an air gap.

Compatibility

House a male separately unless managing a carefully planned specialist breeding setup. Avoid boisterous or fin-nipping fish.

Diet

Offer small frozen or live aquatic invertebrates and suitable betta foods accepted by the individual.

Care

Maintain stable water around 24–27°C and pH 7–8. Confirm the stock’s current water conditions before acclimatisation; do not add salt simply because wild populations occur in coastal habitats. Use a fully cycled aquarium. Check appetite, breathing and equipment daily; test water regularly and keep ammonia and nitrite at zero. Make regular partial water changes with conditioned, temperature-matched water and clean filter media in removed aquarium water.

Click & Collect only: order online and wait for confirmation before collecting from Newlands Home & Garden Centre, Clondalkin, Dublin 22. We do not ship live animals.

Daffodil bulbs

I am absolutely delighted with the service I have received from Newlands . The Order of various daffodil bulbs were delivered the next day ! How efficient was that! I have begun to plant them to have an early spring display. Each of the bulbs look healthy and not soft as sometimes occurs . I would highly recommend Newland for ordering , fast and protected delivery and competitive prices .
Happy planting !

HabiStat Leopard Gecko Substrate 10kg
Excellent

Tried this substrate out of curiosity. Previously my gecko was on Earth Pro Arid which itself is a good substrate, so I didn't expect it to be outperformed. I prefer this substrate by far. It does not give off any dust when dry. When wet it sticks and holds together like sand on a beach, making it very malleable and easy to landscape your viv. It holds humidity very well. My gecko hates sphagnum moss, so I use this in his humid hide and it works just as good, so it's solved that issue for us!

Everything I ordered came packaged very securely with fragile stickers attached to the outside. Which was appreciated as bulbs were also in my order. Order arrived quickly too!

I am really pleased with the pond plants I purchased from Newlands, it was the first time I had done so. The plants were in good condition, and I have no hesitation buying more plants in the spring for my pond from them.
