Can I Add Another Clownfish?

I currently have 1 clownfish and a pygmy angel in my 20 gallon long. I will be taking my pygmy angel out so I would lke to replace it with a different fish. My clownfish is a little over an inch long and I don't know if it is an occelaris or percula. Occelaris have thin stripes right? Anyways Is it ok to go get another clownfish and put him in or will they fight?

 

Yes you can get another perc or occy clown, just make sure it is a different size than the one you currently have in the tank, preferably get a smaller 1 but a larger 1 is ok as well, They will pair up and the larger more dominant clown will become the female

 

Will it be ok to get an occ and perc pair?

 

I would get one just a bit smaller just in case your current lone clown has become a female.

You can get either type at this stage but if it were me I would go with the Occelaries, so your pair looks like a pair.

If your last post is in regard to have more than 2 Clownfish in the tank, than no not a good idea. They will all get along initially but as they become sexually mature they will become aggressive.
