Killifish

[Doodles]

I just have a few questions about my Killifish. I bought him a long time ago and put him in my tropical tank (75 gallon). Im not positive but I think he is a Euro Asian Killifish, he's yellow.

Anyway, he was pretty nasty so Im just wondering are they aggressive or is it just my bad luck? I read that they are peaceful. He is now in a 10 gallon alone and Im just wondering if I should try to put him in with my balas? Then I will have another 10 gallon that is free.

I don't want to give him up because I kind of like the little sucker. So if he has to stay in the 10 gallon by himself that alright, just wondering about other peoples experiences with these fish.

10g's is fine. They live in puddles in the wild. As long as he's no bigger than 2.5 inches then yes.

i agree with Cichlid Man

Thank You, I feel better now!

That is making an assumption. The fish he has is Aplochielus Lineatus, otherwise known as the gold wonder or gold panchax. These certainly do not live in puddles in the wild, the eggs are not capable of surviving a dry period and in fact these live in permanent sometimes quite large bodies of water. This is a large killi reaching almost 4", and the males are aggresive so what you have is common behavior. However, I think he would do alright with the sharks.

Im a she, LOL.

Went I went to buy him, they said he was non-aggressive and a very peaceful fish! That sure isn't true. But I like him and couldn't find myself bringing him back. If it doesn't work out with the sharks what size tank does he need? Im actually going to try to put him in the tank right now. Cross your fingers it works!

Saying that he is a golden wonder panchax is also an assumption. Most true killie fish's eggs can survive being dried up in the dry season in the wild. If the fish is a golden wonder then I won't recommend keeping it in a ten gallon as they grow too large.

Calling it a Lineatus is not that much of an assumption, He says it was European or Asian. He says it was Yellow, which really narrows it down (the only other one I can think of is Fundulus Chrysotus or maybe Fundulopanchax Fallax but the chances of them being in a LFS, practically none), Lineatus are commercially bred and stocked by almost every fish store in the country. Therefore I am 99.99% certain that it is one. This fish along with MOST other killis are not annuals and the eggs do not take drying very well. Try drying up some Fundulus eggs, they will not take it well. Even most aphysosemion eggs do not take being put on peat veyr well, the only ones that do it well are the nothobranchius and the various annual south americans, both of which are highly outnumbered by their nonannual counterparts.

I think a ten gallon is perfectly fine, I have kept and bred this fish and a couple other large killis in ten gallon tanks without any trouble at all, except their propensity to jump.

[fishguyeric]

I forgot, it is also aggresive which is a trait that not many killis have, this being one of the two aggresive killis I can think of.

It's definitely a gold wonder.

What size tank do you recommend if he does not work out in the bala tank?

Ya, I noticed that he jumps like crazy! Sometimes it scares the crap out of me.

It's good I have extra tanks around in case of emergencies! He was quite aggressive with my community fish. I was going to try to put him in with my Balas now but Im not going to be home all day to watch to see if they get along. I will do it tonight and tell you how it works out. I hope it does, if not and he get's to big for the 10 gallon I will get him another, probably just a 20 gallon though.

I'll take a picture of him in a bit and post so you can him.

By the way Im a female guys., lol!

[Doodles]

oops, sorry double post!

[Fishboy93]

I have 2 gold wonder killies and they are very docile they just skim the top in wait of bloodworms....

[fishguyeric]

I imagine that individual variation exists within the species. MY male was also an agressive fish, holding his own with some tropheops sp. and later with a pair of blue acaras, thought the male later ate him.

[Fishboy93]

Yeah mine are in a community set up so they dont have to much to worry about...

[Doodles]

Well I put him in with my balas and they all get along great! Im happy I tried it. I guess it sounds like it just depends on the individual fish, like fishguy said. He is way to mean for my "community" fish but this worked out great.

good to hear!
