Question

I was at the pet shop today and saw fish called 'kilifish' which where in a coldwater tank, I tried researching kilifish and it comes up with loads of diffrent kinds, It also says that they are algae eaters, and eat hairy algae, Does anyone know anything about them or have information abou them?

Thanks

Also - I had algae eaters before that liked to suck the slime of my goldfish so i got rid of them, Will the kili fish do this?

Answer 1

There are hundreds of killi fish so you need to look again and see what type they are before anyone can help you much.I have a pair of golden wonders and they are great but need a 20 gallon tank and will eat smaller fish if they get the chance but some species are much smaller. You could also try describing the ones you saw ,golden wonders are quite common.

Answer 2

There are literally hundreds of species of Killifish, so saying they have a "Killifish" is pretty much useless. There are Kilies like the Florida Flagfish which are AMAZING at devouring hair algae and stick to the middle-bottom part of the tank (though they get about 4-5 inches), and there are inch long species that could easily be kept as a pair in a 5 gallon tank. One of the most common Killies is the Golden Wonder, which will reach 4-5 inches, so that is likely what you saw in your pet store... Without knowing the species, we really can't tell you anything.

EDIT: Killies do not have sucker mouths, so they will not suck the slime off of your Goldfish (or any other fish), but some of the species of Killifish (like Florida Flag Fish) can be fairly aggressive and others can be quite nippy.

Answer 3

nope. killifish are topwater omniverous micropredators for the most part. they stay small but are extremely colorful. they are perfect for smaller tanks. keep them only with their species. killifish species have been known to literally breed daily. they lay usually 1 egg per day. to raise the fry, you'll need a seperate tank, because the adults will eat them.
