How fast do fish grow? (generally)

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.
