    I have a 55 gallon and right now have 1 clown, 1 sixline, 1 yellow watchman, 1 yellow tailed damsel and 3 chromis, totally right now about 12-13 in. I know there is no specific rule for the amount of fish you can keep, that's a different topic. What I want to do is add one last fish, either a flame or coral beauty angel. I feel that because my fish are small, I can get away with another. But about how long does it take for a fish to reach adult size?

    Aslong as you filter your tank, run carbon and keep up on your parameters, I see no reason why not. Just make sure your filter is good for atleast 3 times the water volume.

    Predator/Agressive fish grow fast because they have to, or they will be eaten. Other fish grow pretty slow.

    Example:
    Pilot fish can grow up to 3 feet, and do most of their growing in the first year.
    Clownfish get to a maximum of 3-6" depending in the species and can take 2-3 years(or more) to reach that size.

    I wander how fast a Hippo tang grows. I would like one, but don't want a foot long one. It'll have to be sold or adopted if it gets that big.

    Hippo's grow pretty slow in captivity because the lack of food for them to graze on all of the time. If you get the blue bellied kind, be prepare for them to nip at your corals when they become adults.

    I have had my fish for three to four months now and have not noticed anything to contradict what Geek has stated. It will take years. And that is good. I am running about 11 to 12 inches in my 90g right now and do not plan on exceeding 20 inches total.

    If you want a hippo, go for it. Get a juvenile and watch it grow. I know my LFS would gladly trade an adult for a juvi straight across. Then you start over and life is good for everyone, fish, humans and businesses alike.

    Well from my experience with one I got at a really small size (apx 1") it more than tripled its size in apx 3 months. It got to the point that I felt bad for it (had it in a 35G at the time) and was able to sell it back to the LFS for more than I paid for it BUT the ***** was trying to catch the guy without disturbing the entire tank - even for a decent size fish that guy could really hide! Just my 2 cents ;)

    As I said basically, the lack of food will stunt their growth. How much and how often were you feeding it? A 1" tang is a very young tang, like most things, they grow the most when they are little. Clownfish go from egg to 1" in a few month, but that second inch can take them a year or so.

    You must have been feeding it pretty well for it to grow that fast, I had one in my FO 90 years ago for quite a few years, finally had to get rid of it because it was just to big, but even then it was only about 6 or 7 inches long. As GDF said they grow in accordance with how much food they are given.

    Most fish will not outgrow their food supply. The bigger they are, the more food they require. Which is why certain fish can reach 2 feet in the wild, but rarely reach 1 foot in captivity.

    On the hippo I really can't agree with Geek. Hippo tangs even if fed a normal amount probably will grow at least an inch per year, maybe a little more. Now if you only feed your fish twice a week (I've known people that do) then maybe they will grow slow.

    We feed our fish 3-4 small servings each day. We also have big skimmers and lots of inverts. ;]
    I've found purple tangs and mimic tangs to be some of the slower growing tangs. Like a lemonpeel mimic tang would be good because it really won't outgrow your tank because their max size is 3.5-4" and that takes a long time.

    I would be a little wary on the angels because there is no guarantee that they won't get nippy on your corals. I've always wanted a rusty angel myself, but have never been willing to risk my corals.
    There are some very nice wrasses that would do well in that size tank. Or a flamehawk. It depends on what you're looking for in your last fish addition.

    Just be sure not to wait until your damsel gets very big/aggressive. And chromis don't usually last too long so you might want to look into some blue-eyed cardinals as a really good schooling fish when the day comes. They maintain their school even after they mature, whereas chromis tend to pick on each other as they get older.


    *** For those of you that need to catch any fish in the future, I'll tell you my secret. Turn your lights on at least 3-4 hours after they've been off and catch your fish while they're asleep. Its a piece of cake. I did it that way a year ago, I caught 35 fish out of a 180 in just over 30 minutes using this method and I didn't even need a net. ;]

    thanks for the advice RG, I also was able to catch fish by waiting until they were sleeping, it does make it much much easier.

    I think they grow faster with a protein rich diet. I know most of the foods are protein based, but when I started feeding them food with higher protein amounts, they seemed to grow faster. It could have just been there time to grow so who knows.
