Congo Tetras
 
Hey guys,
I've really had my eye on Congo tetras lately and was wondering if I have room for 4-5 in my 55 gallon tank. If need be, I would be willing to get rid of the black skirts. The pleco is about 5" and I do plan to give him to a friend with a larger tank in the future tho I think I'll keep him a little while longer for now (kinda attached to him).

My water params are very stable, 0 ammonia, 0 nitrites, nitrates before my weekly water changes are always about 10. PH is 7.5, Gh and Kh are 4. I change about 30-40% per week.

Take a look at my stock list in my sig. Do you think I have room? Any compatibility issues? Any advice and comments would be greatly appreciated.

if your tank is mature and you are as good with the housekeeping you say
then I see no reason not to add them.

Jeanine,
Do get rid of the black skirts, as they will pick at the flowing fins the Congos produce as they grow up.
Your pH and hardness are fine for the Congos. They reach a bit over four inches, but you could have six in your 55. They stay near the top of the tank, cruising about an inch or two below the top of the water. They are pretty hardy fish, more so when they grow up, but need mellow tankmates to thrive and several in their school to thrive.

OK, cool. The tank has been running for about 6 months.

What is a good stocking ratio...2 males, 3 females?

Dave66 04-04-2008 02:07 AM

Doesn't really matter the ratio, Jeanine, and its kind of tough to tell the difference when they are little. There's no infighting by the males. With six, you'll end up with at least one pair, probably two. Like I said, doesn't matter the ratio; all six will get along great.

OK. Thanks for the info!

Dave66, choosing (6)fish in no way assures acquire getting one pair let alone two. In fact the odds of getting a pair when purchasing 6 fish is approximately 72%. Mathematically speaking, the odds of getting one pair of fish is bout 98% when purchasing a group of ten. And only 99% when purchasing 11. The prospect of getting a pair does not reach 100% until you get 13 fish.

The Theory of Potentiality is a theoretical calculation of the probability of chance. It is in no way a given, but is a means to calculate the probability of certain circumstances.

You can tell I have too much time on my hands, eh? Anyone who sits around doing these kinds of calculations, has no life. lol

LoL herefishy. Of course, if I was right picking winners at Churchill Downs 72 percent of the time I'd be a very rich man.
So, nearly three out of four times when you buy six tetras you get both sexes? Good odds, they.
Of course, I've never bought only six . . . .or only 13, for that matter.
And you do have a life. An aquatic one.

I've picked up 2 pair so far. And, there was a 100% chance of getting pairs as these were full grown adults. lol I've got 2 females and 2 males. Here's some pics.

I've posted more pics in the Freshwater Pics and Videos section.

Congrats, Jeanine. :D Congos are great fish. Good shots, too, but I'm sure you know its very difficult to capture the opalescence of the live fish. They still have some growing to do, as the male's dorsal and tail fins aren't as extravagant as they will get.
