You can keep 5 in there without a problem.

One more question, would it be okay to order 4 gobies and julies? Or is it a ton safer to order 5?

In terms of not having all males (or all females), 4 of a fish is a 12.5% (one in eight) chance of all male or all female, while 5 of a fish is a 6% chance.

The odds of getting two pair out of 4 fish is about 1 in 8, whereas the odds of getting two pair out of 5 fish is greater than 50% (i believe).

That's assuming of course that you buy unsexed juvies, and neglects fish personality (i.e. if you have 2 males and 3 females, I was counting that as 2 pair, even though one of the males may not like any of the females or vice versa. If you only have 1 male though, you can't possibly have more than one pair, and if you have all females, no pairs for you!).

As Bob the Tomato would say, "you rolls your dice, you moves your mice..."

I am just looking to get one pair out of each group.

Hold on one second. Woulnd't the probability of getting 4 fish of the same sex be 1/16? Because say if you were to get one fish the chance of it being a male is 1/2, then get another and the chance of it a male 1/2 so one. There for you would have (1/2 x 1/2 x 1/2 x 1/2) which equals 1/16. Correct me if I am wrong, I am doing fairly well in 9th grade geometry

The chance of them all being male would be 1/16. but the chance of all female is also 1/16. so the chance of all the same is actually 1/8

Haha. Alright, I got it. Thanks and sorry for the contradiction.

Where are you getting your stapps from?

[CichlidAndrew]

I am getting them from hotcichlids.com

[CichlidAndrew]

One more question, will there be agression problems with that many fish untill they all pair up?

If you keep cichlids, there will always be aggression problems. Just keep an eye on things in the beginning because your fish may require some human intervention to survive. Are you planning on stocking the entire tank at one time?

[CichlidAndrew]

I am planning to do the whole tank at once.
