How many fish to put in tank?

[wyssj]

I have a 29g Biocube that is currently housing > 30 lbs LR, 40 lbs LS, 3 peppermint shrimp, 1 blood shrimp, 6 hermits, pom pom crab, many many snails of 5 different types and a pair of ocellaris clowns (small, about 1.5 inches), a zoa med frag, a LTA, an unknown hard coral frag and some other unknown soft corals that came on one of the rocks.

I am wanting to get some other fish and definitely more corals but I was wondering what you all though would be a good number of fish to house in my tank?

Thanks for any input.

i think the rule of thumb is 1" of fish per gallon of water so 29"s someone else might have a different opinion because i have also heard that if you have a extreme filtration system you can put as many as you like.

The amount of fish in a tank is determined by a few things, size of the aquarium. You don't want to put a fish thats gets 24" in a tank that is 30" x 12", it will have trouble urning around. The end size of the fish (max length) should be looked at. The filtration, a 400 gallon tank with a hang on the back filter wont support very many fish. You need to make sure your filtration will handle the waste load of the fish added to your system. What you have in the tank. If you have a lot of rock and/or decorations that will limit the room the fish have to swim.

I would look at fish that stay small to medium in size ( 4"-6").

On a more serious note... if your in doubt just add a whale shark... they don't need much room at all, you may get away with doing a mated pair.

Maybe look at some nano fish?  You could house a few more that way.  Just a thought.

thats not even right

rule of thumb is 1" per 10 gallons in a reef tank.  we are about double that in our 90.

if you have a good enough filter to handle the bio load  if not you will be doing alot of water changes

[kattz]

we're stuck doing 15 percent a week anyway...

[HUNGER]

heck the most i can do is 40 gallons at a time

Good info already posted here.  I don't believe in general rules on this topic although some fish simply require a larger aquarium.
Other factors include frequency of water change and ability to handle bio load (lot of liverock).

Alot depends on how many hiding spots you have and how good a filter system you have
I have had large numbers of fish I was told not to put together but I have lots of hiding and filter a turn over rate of 15 times an hour. I never have any problems
