Fish Size vs. Tank Size

I keep a few catalina gobies in my 320g.............Maybe i should downgrade?

Seriously tho,big fish need bigger real estate to get their laps in and to have room to roam.

I would never buy a fish that was going to outgrow my tank with plans to trade it later. It is for this same reason that I don't believe in leasing cars. It just don't make sense financially. With a side of, i believe it is inhumane, thrown in there for good measure.

No arguement that big fish need big tanks. But what about big fish that are still small? Take the Clown tang for example. The fish can grow 15" and LA says it should be in a 250G tank. Do you think a 3" Clown Tang would have enough room in a 150G until he grew bigger and was relocated?

No I do not. Clown tangs are one of the biggest swimmers of them all not to mention their extreme aggression. A 3" clown tang can cover even Gus's 8ft tank in an instant.

Like I said before, certain fish like Tangs, most Large Angels, Lookdowns (Jacks), etc. really need a very large tank size even as juvies.
 
I currently have a Niger Triggerfish which its requirements are 180gal, not reef compatible and labeled as aggressive. Does not pick at any of my corals. He has been with me for almost 2yrs and his size is almost at 3.5” or 4” in a 75gal. I honestly think he won’t get any bigger but FAT only. We all know that these fish can get BIG within time if given the room to do so..

Will growth STOP as some point with space given?
Will he still grow after 2yrs?
So are the standards set by measurements at sea or home aquariums?

Unfortunately part of the issue goes back to the LFS who needs to cover costs and will sell a fish even if they know the tank it's going into isn't suitable.

I am a firm believer of buyer beware. I do not feel sorry for the end user that is duped by the LFS. The LFS is there to make money, end of story. The inexperienced and or experienced sw keeper should not be making impulse buys. Even when people do have knowledge to avoid stupid purchases they still make stupid purchases. The very question hints at a much deeper question about human nature that will probably be debated till the end of time. People tend not to care if there is no accountability. The hobby would be very different, if for instance, killing a fish because of negligence carried the same sentence of killing a child because of negligence.
 
All seriousness there is research to the effect that you can stunt the growth of animals, fish included, but limiting habitat space. Yellow tangs are a good example, people love to prove the theories wrong by 40 breedering them and they stay small....but is the fish healthy? People that stay small and twiggy look pretty unhealthy to me.

My 2 cents:

Right and wrong is in the eye of the beholder, just expect scrutiny if you put tangs in biocubes :)

Your money spend it how you see fit
 
There seems to be some mis-information in this thread, so Ill just vet it so everybody has accurate information.

A 3' square cube is a much different aquarium than a 180 long or even a 300 gallon tank. Typically these long skinny tanks are maxed out at 8' long if constructed out of glass.

This means that a fish can swim for 8' before having to stop and turn 180 degrees and swim back the other way.

A cube however has enough room to allow the animal to swim essentially laps. Calculating from the bottom of the front corner, to the top of the opposite corner of a 3' tank is over 10 feet in circumference. Not to mention the fish never has to stop or slow down.

Would I put a sailfin tang in a 30 gallon tank at any age? No, but somebody attempting to draw a hard line at some artificial number of gallons is no more acceptable, especially when failing to consider all of the variables. Age and size of the fish included.

Just so everyone has a full set of accurate information, the poster trying to vet The info for you houses multiple large tang species in a 3' cube. Their opinion may be biased.
 
Cool..so looks like I'm ok with my 8', 440 gal tank with a few of the above tangs...for obvious reasons have avoided the clown, sohol, unicorn and vlamanigi tangs..
This has been helpful..thanks.

With a tank like that I think you'll be more than fine!

I'm going to have to disagree. Bill, I really think you should just break down that 440 and set up a nice 800+ custom setup. Maybe use the 440 as a refugium or garden planter or something like that...

Kiddie pool? Hell even my large rear could probably fit in that tank.
