Behaviour & Compatibility
Compatibility must be checked for the adult fish, not its size at sale. Check every proposed companion with our aquatic team and allow extra territory for breeding fish.
Feeding & Nutrition
Omnivorous, feeding on high-quality flakes or micro pellets, along with frozen or live foods such as daphnia, brine shrimp, and bloodworms. A varied diet helps maintain strong colouration and health. Feed measured portions rather than allowing food to accumulate; juveniles may need smaller, more frequent meals. Make sure bottom-dwelling or shy animals receive their share.
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.
