How long do you wait to find the missing fish?

[reacclimating 2 the hobby]

In short, I added two clowns, a lawnmower blenny and a clown goby to my tank. The clown goby has not been seen since. My scape isn't hard to move, but I'm not a fan of going in my tank more than I need to. How long do you wait?

I will refer you to my experience, If it goes two weeks and no sight of the fish, then the cuc has done its job. Happened to most of us at least once.

I can’t speak to clown gobies, but I recently added a Diamond Watchman and it took a solid two days before I saw it. Then it was only occasionally for another several days. Look for the telltale changes in your sand such as voids or hills of sand covering rock as “proof of life”

I haven’t seen my hermits since I added their new shells. It’s been about a week I think I saw one today though

I'm watching for ammonia for proof of death

Depending how large your tank is, how mature and the size of your cuc, you may not have an ammonia spike. I never have when a fish passed. Especially one the size of a clown goby.

My tank is relatively new. I don't have a cuc, because I left my lights off for the entirety of the cycle and there is not yet anything to clean. Except possibly this fish. Otherwise, I wouldn't be concerned.

I had a blue head wrasse that disappeared for weeks. Thought the jerk was dead and eaten then one morning he was out swimming around continuing his reign of terror on my hermits and snails.

I have 2 clown gobies in a small 5 gallon tank with one large rock… didn’t see either for about a week, that’s how well they can hide in the rock. I’m assuming your tank is bigger than a 5 gallon, at which point a clown goby isn’t likely to be catastrophic if it were dead and not removed. Like someone above said, your cleanup crew should have taken care of something that small if he is dead. If you have one, I’d check the sump area first before I messed with moving any rock. If he’s not there or around the tank, I’d assume he’s still hiding or a goner.
