They are compatible. Dragonets generally only attack each other and their toxic skin makes them immune to aggression. So long as you manage to feed the mandarin it’ll do fine.I have (30"x18''x12'') 30 gallon tank, 2in sandbed, no fuge, wavemaker, ac70
currently stocked with: 2 clowns, 1YWG/tiger pair, 1 additional tiger pistol shrimp.
sandbed is pebble and finer grain sand, plenty of rocks and tunneling area along sandbed, YWG and shrimps have made their paths
Can I add a captive raised dragonet / are they compatable with the YWG also being a bottom dweller?
