If you are unsure, ask us to check compatibility before purchase. Tracked UK delivery and live-arrival cover apply under our livestock delivery terms, but the suitability decision still needs to match your own aquarium.
Nothing here is written as a guarantee of temperament or compatibility; it is a careful rewrite of the facts already held for this listing.
