Who do you have on guard who's battling day in and day out to keep your tank running smooth perhaps a fish ugly as snot but too good at what it does? Perhaps an unexpected gift..wow he eats aiptasia? Perhaps not a fish at all ?
Just livestock please no equipment , routines etc.
For me my melanarus wrasse is a champ I'm sure I would be riddled with pests if it were nt for him ...true workfish
Who's on guard for you????
Pics welcome!!
