Livestock

Know what's swimming before you drive out

Our stock sheet is now a real page — searchable, sorted by tank number, with current prices. It comes straight from the list the team updates in the store, so what you see is what's on the racks.

  • Search by species name — “wrasse”, “tetra”, “shrimp”.
  • Filter to saltwater, freshwater, bettas or nano inverts.
  • Tank numbers included, so staff can walk you straight to it.
