Adding a fish-which one?

[roinesaad]

Hi currently have
2 x Clownfish
1 x Royal Gramma
1 x Nano Gobi
Hermit crabs
Fire shrimp
Triangle crab
Pair of snails
All seem to be doing OK
What fish should I add, looking for something colourful
TIA

Looking back, it seems you added your first fish about 2 weeks ago? And that addition caused some measurable ammonia? And this is a 13 gallon tank? That looks like more than plenty of livestock.

Size of tank is important. Do you have live rock and live sand in it. I am new to salt and made the difference.
I found that Turbo Snails make a huge difference and keep the tank - no ammonia ever.

With a 13g tank you're already over stocked.

It looks like you've got some awesome stuff already. Given the size of your tank, it may not be best to add another fish.
