kribs

I have a male and female kribensis, when I 1st got them they seemed to get along great. When I got home tonite though I noticed that she was chasing him anytime she saw him. Should I be concerned?

you sure its a male and female? and how long have you had them?

they are.. got them on sunday. The female is much brigter..the males tom fin is longer and they are the same size

ok so im not sure...they could both be females I guess

normally it is the male who gets the bright rosey belly

well the other isnt very bright at all.. they look diff but not enough to be able to tell.. Guess I need to wait it out?

thats what I would do, just keep an eye on them to make sure one is not getting to beaten up, chances are right now they are just figuring out where each others territories are.

thanks for the advice.. im gettin some more plants this week so the territories will be getting rearranged.. and there are lots of other fish in the tank to so the other one can kinda hide and be ok and come out and not be seen

yep, thats what I do when I have more than 1 (normally I do have more than 1, but the second one didnt make it past QT, so after I move and get set back up, I will be getting more).

if they both are female should i add a male and keep both or add a male and remove a female

Some info I dug up
http://freshaquarium.about.com/cs/africansgeneral/p/kribensis2.htmSelecting a Pair:

Selecting a Pair:
If you wish to breed P. pulcher, finding an established nesting pair makes the relatively simple process. However, you can select your own pair, as they are relatively easy to sex. Choose young specimens that are healthy and robust. P. pulcher reaches sexual maturity is as little as six months (females mature faster than males), so make inquiries - often the store owner knows the age of the fish.
Females have shorter rounded fins and a broad yellow band across the top of the dorsal fin, are smaller than the males, and have a more rounded belly that is bright red/purple when they are ready to spawn. Males are longer and thinner with fins that end in distinct points. They are less brilliantly colored than the females, especially the belly. Take care to get the same species of fish. There are several closely related species that may look similar, they will not spawn with each other.
Once a pair has been established do not introduce another fish into the tank. Males will invariably fight, and even two females will quarrel for the attention of the male.

good information..thanks!

Gender : The females are usually more colorful and possibly smaller than males of the same age. The dorsal fins on the female may be rounded whereas they can appear pointy on the males

although, when I had my breeding pair 10 yrs ago, it was always the male who had the rosiest belly out of the two.

I have a mated pair of kribs that are killers. They have to stay in a tank of there own. It's the first pair I've had that are so mean. At the moment I have 27 1.5 to 2" males the water must have been to warm because the whole batch is males not one female. Each pair IME is quite unique and have different personalities and I've had several pairs over the years. Be sure to have several caves for them to hide in not just plants.

the higher PH the more males to be.
the lower the PH, like under 7. then more females.

i think i read it online somewhere.

I have read that also but I have a low PH 6 .8. Temp in most cases is the reason for unusual male/female ratio in fish. They breed during increased temp due to an Ich outbreak so the temp was at 84 for 2 weeks.

high temp huh. mine havent breed for me yet. i guess ill have to up the temp a bit then. i had them for over a month now.

alan, up the temp put a few rocks to make cave and feed them frozen food.... i had fed mine to weeks ag0 and now i have fry... the males dorsel fin is more pointy and the female has a bright pink belly u will notice it more after feeding frozen food... let me know if you have any questions

i have all the stuff you recommend. the temp is going up tonight.

thanks

they should breed in a temp about 76-78 degrees.

ok.
