From what I've read they should be kept in 20g minimum. They don't stay where you put them, usually, which can make it hard to keep other corals in the tank.
The problem is they are very sensative to fluctuations...this is your first salt water tank, your are going to make some mistakes, it happens, I just recommend a larger tank for the animal, they do better and so do the rest of the inhabitants.
i say its been in there for about a good 2 years fromt he condition of the tank that i was in. he may have split a couple of times that guy just used it as a display.
it seemed fine sayed in one spot but the other BTA (green i think) was in the corner and the tips was in front of the powerhead.
the RBTA was about 6-7 inches long but i bet i can stretch beyond that.
Sorry to poo poo on your parade.......I think a 10g is way too small for two clowns....one maybe.......and totally forget about the anemone......bta's can get to 12" or more in diameter and in a 10g that would be crazy and somewhat cruel to the animal beside the fact that you would giving it a death sentence. Any anemone is that small of a tank is a disaster waiting to happen. If you really want one there are plenty of artificial ones that look really really good........
first of all just cause a lfs has it doesnt mean its right/safe... they actually have the means to just put it in another tank if it poses a threat
have we pointed u in the wrong direction yet???? nobody hear has any reason to lie *crazysmil i wouldnt recomend putting any type of anenome in a 10 ....... not only would you be wasting your time and money on this anenome but youll also be wasting all the time and $$$ u have in this project so far...... you seem to be pretty smart and do alot of reaserch but why not actualy listen to what u read??? i wouldnt even try to keep an anenome in a 20 IMO.... i couldnt imagine having a 12 inch anenome in my 10 gallon*twirlysmi it'd be like a anenome tank lol ... and id only get 1 clown 2 seems a bit much...ive got just 1 clown in my 10 gallon and he actually hosts in sum of my zoos!!!
btw the reason u shouldnt have it isnt only cause the tank isnt big enough but also because the water is way more concetrated in such a small volume have you read the sticky yet??
