Rock's mostly covered now and the frags have filled out a lot more than I expected. Work's been slammed so I haven't had much time to fuss over it, but it's holding steady on its own. Happy with where it's at.

first fish

Added the watchman goby today, bag was floating up top to acclimate. He shot straight into a gap in the rock and didn't come out for an hour. Saw him poke his head out tonight, seems fine.

A 75 with just the one goby right now... Are you planning on adding more fish once it's more established, or keeping it minimal like this?

VValentina PhamSep 3Question

Just the one watchman goby so far or are you planning to add a pistol shrimp pairing down the line?

Tank owner replied

Just the goby for now. Thought about a pistol shrimp pairing but haven't pulled the trigger, might add one later if I find a good one.

Just one goby in a 75? That's a big tank for him lol, does he claim a whole corner or stay in one spot

Tank owner replied

He's picked one spot near the rock gap and mostly stays put, just pops out to feed. Wouldn't mind if he explored more of the tank but he seems happy there.

No plants in here right? Just curious what that rockwork is made of, looks cool

Sofia PerryAug 9Question

How long has this one been running? That goby looks really settled in already, curious how the cycle went with just seiryu stone as your only hardscape.

Seiryu in a saltwater build is an interesting choice. Any issues with it affecting your alk or ph?

Just one watchman goby in there or is a pistol shrimp coming later?
