Mustard Halfmoon Siamese Fighter Male (Extra Large) | Betta splendens

Choose the aquarium for the adult animal and its companions. A mature filter and stable, species-appropriate water conditions are essential.

At a Glance

Housing & Setup

Enclosure dimensions are length × depth × height unless stated otherwise. Plan for the adult animal; larger, suitably furnished housing is encouraged.

Behaviour & Compatibility

Never keep male bettas together. Avoid fin-nippers or fish with conspicuous flowing fins; a planted individual aquarium is often the safest choice.

Feeding & Nutrition

Feed a quality betta food in small measured meals, supplemented with suitable frozen or live invertebrates. Avoid oversized portions, and remove leftovers. Confirm the current feeding schedule at collection.

Routine Care

Check appetite, breathing, equipment and water temperature daily. Test water regularly; ammonia and nitrite must remain at zero. Make regular partial water changes using conditioned, temperature-matched water. Rinse biological filter media in removed tank water, preserving the filter bacteria.

Important Before Buying

Cycle the aquarium before collection. Confirm the current food and water conditions with our aquatic team and acclimatise gradually. Sale size is not adult size; stocking and filtration must account for the full-grown animal.

Live Animals Are Click & Collect Only

We do not ship live animals. Order online and wait for confirmation that your animal is ready before collecting from Newlands Home and Garden Centre, Clondalkin, Dublin 22. Have the enclosure prepared and its conditions checked before collection.
