2 themed stocking ideas for 180-gallon

1. Show-tier SPS reef

  • Full tang school (yellow, purple, kole, naso)
  • 1x Pair Designer clownfish
  • 1x Six-line wrasse
  • 1x Pair Banggai cardinal
  • 1x Yellow watchman goby + pistol
  • 1x Mandarin dragonet (mature tank only)
  • Premium SPS collection (named WWC + Tyree morphs)

Notes: The reef tank size most pros aspire to. Premium lighting (Radion XR30 G6 array) + ICP-MS testing + premium dosing.

2. Multi-cichlid community

  • Tanganyikan rift lake setup (frontosa colony, multipunctatus, julies, comp shells)
  • Aragonite sand + rockwork
  • Hard alkaline water

Notes: Tanganyika biotope. Frontosa get 12+ inches. Multipunctatus catfish breed in shell-dweller territories.
