Is My Tank Over Crouded

18L = 4.75 US Gallons, so that means you can have a total length of 4.75" of fish (taken as there expected adult size) The bumble bee gobies count as 2" each so your tank can only support 2 of them without the catfish.
Are they fully grown yet? If not I wouldn't worry but would be planning a larger tank for when they do grow past a total of 5 inches.
Just to add I'm no expert - just setting my tank up and have read a fair bit recently - so just repeating what I read!

the one inch of fish rule is a load of rubbish. Could you get a 30 inch pleco in a 30 gallon tank? No. That rule also doesnt take into account fish waste. One goldfish produces more waste then 3 or 4 neon tetras put together, yet, in a tank that size, you couldnt have one goldfish.
IN a tank that size, its best to go with small fish such as tetras etc... you could reasonably have 8-10 in a tank that size, maybe even a few more if the tank has been matured for 6-8 months. Go for small waste producers.

Are the BumbleBee Goby's the brackish kind or the freshwater kind ? also what kind of catfish is it ?
You are over stocked as TF said and in reply to drain the 1" rule is used as guidance it's normally 2" to 1G of water to allow new fishkeepers the room for unexpected mistakes and changes in the water param's so in this case the rule is needed. You also state he could keep 8-10 tetra's? I have a 17G tank and was told if i put my 20odd neons in there i'd almost be at full capicity
The best thing you could do would be to
1 .Get pictue of the catfish so we can ID what it is and also find out with species of Bumblebee goby you have
2 Upgrade tank or rehome fish and get a Betta which would live happily in that tank

I respect the advice that the more experienced members give here, as my experience in keeping an aquarium is very limited. Some of the advice given has a second aspect to it, which seems to be about quality of life for the animals you are keeping. So, although I could keep two 6 inch Goldfish alive in a 5 gallon tank (which I do) that does not mean it is a healthy environment for them (I am moving them to a pond soon). I am locked in a constant battle with pH from all the NO3, so this little tank probably takes more work than a really large tank. (Daily water changes 
) Here is a picture of the poor Goldfish, yearning for a new home…
I suspect somewhere in between is the realistic number of fish you can keep. Having learned so much about the cycle from keeping these Goldfish for only short time has really prepared me well for the change to some new fish once they are re-homed. I will probably put 5-6 Neons in my daughter’s 5 gallon tank. People say they produce far less waste then the current fish, so I am confident I can maintain a great water quality tank for them.
Anyway, hope that offered some guidance. In the end, listen to the pros and be realistic about your abilities.

Yeah, bumblebee gobies are brackish. And catfish usually don't tolerate salt.
That tank is big enough for a betta.

My camera is broken but this is exactly what he looks like and in another thread they said it was the C. schultzei kind but bred to be black http

This is on a site I found
The First Thing
Bumblebee gobies come in two distinct species. Both of these species are really best suited for brackish water, but one type can survive quite well in fresh water. For those of you who want to know the precise difference, here it is:
The Second Thing
The Brachygobius xanthozona has perfect unbroken black stripes and is best suited for brackish, but will tolerate fresh water much better than the other type.
The Brachygobius nunus has less well banded stripes, and occasionally black spots or broken stripes. It is not very tolerant of a fresh water environment. Technically its common name is the Golden Banded Goby, although I have not once seen these two species clearly distinguished when on sale in fish stores.
They are the first of the two types if this info is right. They are doing fine and these gobies on lots of websites have said they grow max five cm most common answer is 3 cm though mine are currently 2 cm.

Not at all; it's intended primarily for newcomers to the hobby so that they can grasp the basics of fishkeeping and - hopefully - get through the early weeks/months of fishkeeping without mishaps. I'm sure experienced fishkeepers know more than newbies and understand it's not a hard and fast rule for everyone.
