killifish?

[Sgooosh]

hello! i'm wondering if i can keep killifish in here:
75g
20 or so juvenile guppies
a few baby swordtails and 2 big ones
4 pearl gouramis (i should only have a pair but i knew that too late )
some cories


also what type of killifish? (not least killifish)

Most killifish come from soft acid water.

What is the GH (general hardness), KH (carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm, dGH, or something else).

Depending on what the GH of your water is, will determine what fish you should keep.

Angelfish, most tetras, barbs, Bettas, gouramis, rasbora, Corydoras and small species of suckermouth catfish all occur in soft water (GH below 150ppm) and a pH below 7.0.

Livebearers (guppies, platies, swordtails, mollies), rainbowfish and goldfish occur in medium hard water with a GH around 200-250ppm and a pH above 7.0.

If you have very hard water (GH above 300ppm) then look at African Rift Lake cichlids, or use distilled or reverse osmosis water to reduce the GH and keep fishes from softer water.

I keep my killies in 10-20 gallon tanks (40 to 80 ltr approx), not filled to the top. Most species are from shallow water with few to no other species around, and they tend to hide in community tanks.
You could get norman's lampeye (Poropanchax normani). Golden wonders are, IMHO, awful beasts that end up looking like fat cigars (neon yellow cigars) and are predators, but they can live anywhere large enough and get along well with pearls. Adults have wide mouths and an eye for young guppies.

I wish everyone had killies. But it will never be because the beautiful species (there are only maybe 100 stunners) need their own tanks. We can get around Bettas having their own tanks because of their fins getting shredded, and their sometimes desire to murder, but we have to think the same way about Aphyosemion, Fundulopanchax, Nothobranchius and SA killies. There is one exception that could do well - Fundulopanchax gardneri. They are more aggressive to their food (most killies slowly starve in communities) and can handle themselves if their tank mates get rude. They themselves don't look for trouble either. And they happen to be beautiful and tolerant of heated tanks.

i remember gh is 150 i think
it's a little lower because of rotten plant leaves and such

i think ill do gardneri... they seem to be more competitive, and seeing as i have guppies and harlequin rasboras, they are very fast and aggressive at fighitng for food

Gardneri will probably eat guppy fry. But the adapt well to most water, even if they breed better in medium to soft water.

i know, i buy fish small so that when they grow up they are used to not eating them

I'd say go ahead in my eyes, how much guppy fry do you want? I would recommend a juvy killie.

all of the guppy fry! thanks!

what's the scientific name for a juvy killie? i couldn't find anything on the Web

sorry I shortened "Juvenile". (juvy)
I would recommend a golden wonder (Striped panchax) they have a laidback and chill temper. id say maybe even a pair but that may be pushing it.

I think my tone delivery was off. sorry

I was implying that a killifish could control the next generations of guppies, that is if you leave them in the main tank.

they are very cool, do they grow very big? because a pair might be pushing a 75g?

Nope no really they will typically reach 4 inches in length.

oh ok, wdym a pair is pushing it then?
*sorry, i might not be getting the point here lol

my killi would eat houseflies during the summer. 1 killi I'd say OK, 2 killies I'd begin to worry about my guppies. but granted, it's been a few years since I've kept them. now I really want to get back into the killifish game.
