I noticed that your
ammonia reading is .25 - I know that sounds minuscule, but that is actually enough to kill off your fish, especially gobies, which tend to be particularly susceptible.
If you're not already, you may want to commit to daily water changes of 25% and regular testing until the tank is safe, so your bn don't suffer.
So, once your tank is ready (no more ammonia or nitrites & nitrates less than 20), it seems like these cute little buggers would be a lot of fun.
From what I've read, these guys are tiny - less than 2" and they can vary in water condition, seemingly happy in
FW or brackish, so if you plan on making the 57 gallon a strictly peaceful and, not including bn, fairly small fish tank (just because anything too big might chomp on your gobies), then in my opinion, they would make a great addition to your tank. And... pictures please
EDIT: Bumblebee gobies are NOT appropriate for your tank. They are strictly brackish.
Edit #2: I'm SO jealous. Lol. Never seen those little guys around here.
