well the tang i saw the at the store looked about 1.5 inches long. i have a 40 gallon tank. i was thinking of keeping it only for a little while and then give it away when it gets too big.
40 gallon, I planned on keeping it until it got too big and then giving it away.
You should be fine. Just remember, for as much algae as a tang eats it will give the nutrients right back. They are dirty fish. Also, catching fish sucks so that is always something to consider anytime you add a species short term.
okay so do you thing it will cause my nitrates and other nutrients to rise in the long run? unless i keep doing water changes or have a refugium?
I would not be concerned about aggression right now as all of these fish are pretty small. As the clownfish get bigger and become breeding adults it's possible they could become very territorial. As the tang gets bigger and becomes an adult it's likely it will become aggressive in tight quarters. It's too hard to say when that will happen, but in this size tank eventually it will happen. Right now it's highly unlikely there would be any issues. Of course there's no guarantees in this hobby and if you're not quarantining fish you're taking a risk of wiping out your fish and having to fallow the tank. If you play the parasite management game, fish fighting active infection are often much more aggressive as they are irritated. I only mention this as an aside.
I was surprised how dirty tangs can be. Removed powder blue and now struggle keeping nutrients. He was so food driven I put the trap in the tank with food and caught him within 2 minutes. Others not so easy to catch
