Hello!
I'm a new reefer, with a 20g IM peninsula that's been running a month now. In it we have an emerald crab, 2 nassarius snails and one astrea snail, didn't want to go too heavy on livestock right away
Our cycle seemed to have finished very quickly, both we and the LFS were testing water weekly if not more often. We had a small spike around week 1.5, and were clear from there.
22lbs/live rock, I believe what was 10lbs of live sand, a filter sock & chemipure (LFS recommended) is what we're running. Tank is kept at 74°F, salinity 1.024.
We supplement feed the crab once to twice a week with pellets, he loves them.
The problem is, last week we got a yellow watchman goby! LFS said he eats frozen well and might go for the crab pellets too. We brought him home, acclimated for an hour & 1/2 by adding quarter cups of tank water to his water every 10-15m, taking out half when it got full, etc. Dropped him in, watched him swim around for an hour, then we left to run errands. We haven't seen him since!
We dropped some brine shrimp every other day, absolutely no sign of him. Everyone else is happy as can be. Two days ago (day 7 of him supposedly being in the tank) we had a small ammonia spike - up to 0.25ppm, nitrites fine and nitrates @ 5ppm. We did a water change, then tested the next day (yesterday), same parameters. We have a really nice copepod population on our glass right now, and I know for a fact the little YWG didn't jump. The Nass snails and crab haven't been seen eating a carcass (and we can't find him ANYWHERE, no burrow that we can see, nothing floating around...). We have a lot of holes in our live rock, and we don't plan on tearing apart the tank to look for him.
Is it possible he is alive and well living off whatever he's scavenging and the ammonia incr. is some food we haven't been able to pull out, or is the spike telling us he didn't make it?
Thank you!
