How many fish in 20g

[clownfishluvr123]

I currently have a 20g standard tank with 2 clownfish, a firefish, and a Tailspot blenny. I was wondering if it’s possible to add a 5th fish and if so is it possible to add a pearl jaw fish. Have found them to be quite cute lately. Is it possible to get one?

How deep is your sand bed? Pearly jawfish need at least 4 inches to burrow. That aside, if you have enough filtration you should be okay since all your listed fish occupy relatively different niches

Personally I would not, I think you have a good mix of fish and pushing your luck to add another. 4 fish in a 20 is a full tank, the fish will grow in time. if you really want another fish, get something like a neon goby or a clown goby, something very small.

As mentioned above, jawfish need a thick sandbed.

I have 4 fish in my 20g, I could maybe add another small fish, but I feel like my tank is full with those 4. I personally would either stick with the fish you have, or get a small goby. Skip the jawfish

I'd stop at four fish. Especially with your clowns in there.
