Got a tankfull of these little sunfish. Over the last few weeks fry of various sizes have begun to take it over - the parents seemingly ignoring them. I removed the adults a few days ago in order to grow the young fish on for selling at auctions in the coming year.

I was checking them out this morning (using a magnifying glass) and was watching one of the "larger" fry. It was about 10mm or so. There was a smaller fry in front of it, they were face to face. The little one was about 6mm. You can no doubt guess what happened next. The larger fry gulped the small fry down. It couldn't quite manage it all and the small fry's tail was sticking out for a minute or so until it worked it into it's belly.

So yes, if breeding these it does seem that the parents ignore the fry. But you can be sure the fry don't ignore each other.

Yep Graham, I have to second that!

And frustratingly it does not make the slightest difference if you saturate the tank with live food much more convenient for their size, they just can't resist snacking on their own kind!

What's the natural habitat of this species like? Any other fishes?

Don't have sources to hand Matt, but did a bit of reading about these guys a while ago. Distribution here - http://eol.org/pages/207190/maps.

Typically in overgrown ditches, pools and swamps in dense vegetation and leaf litter, lays eggs preferentially in hornwort. Presumably overlaps with various killifish, but I don't know anything about them as a group so wouldn't like to name names! Think I read somewhere often found with gambusia.

 

Hopefully someone else can be a bit more authorative!

Hi Matt,

the only helpful thing I could ever find is here. It's from the German fish keeping magazine DATZ but I'm sure you'll cope. Smile

At the bottom of page 3 there's a table with sympatric species.

Unfortunately I know next to nothing about our native fishes. Need to change that!

This one is on my list to try this summer (hard to find them this time of the year).

Yeah Jim,

especially because you guys got a couple of real stunners swimming right in your backyard. Smile There are quite a few species I'm still interested in too. Especially the "darters" that Stefan seems to be quite busy with these days. Smile

Etheostoma would be really high on my list as well but far too warm here. Frown I do accept full responsibility for Stefan's current geekery though!

Jim, what native species live in your area?

Mostly salmonids Matt. Nothing that would be in the aquarium trade.  This one is interesting though I haven't seen it.

And this guy, I think it's cottus asper

probably not, at least for some species. My older orangethroat darter group is still ok after 3 years of being kept at 70-80F (3 years is supposed to be the lifespan).

.....

Ugghh.... the guy I'm getting darters from got some of Elassoma evergladei in now... what does one need for a group of 6? planted 5g?

Hi Mike,

I'm keeping a group of 5 in a 27 l cube and wouldn't go with much less. That is if there's more than one male. They don't do any damage when sorting out who's boss really but do get quite distracted from the "main business at hand". :-)

And plants, YES, ..... MANY!

Regards

R.

The water temperature rises to 90°F+ in the summer, and for an extended period of time. Lost the Gastromyzon and Acanthopsoides in August this year. Frown

Yuck, this is bad indeed....

I use A/C during the summer to keep the temperature under 82F...anything higher would kill off some species...

Still, not hopeless, darter-wise, Etheostoma fusiforme should be able to handle this.

http://en.wikipedia.org/wiki/S.....amp_darter :

No other darter is found as far south as E. fusiforme.

Plaamoo: if you want to give darters a try, check these guys... this is the latest fish I got. Very nice and (I hope I am not making this up!) they seem to be making a faint click when surface-feeding.

They should be fine in a loach rivertank and they don't take much space. No idea what would happen to Sewellia fry with these guys around.... probably nothing good.
Even better would be to mix them with gobies.

In re Elassoma: my current problem is that there is more than one species. I can get e.evergladei
or e.gilberti now, but it should be possible to find Elassoma okefenokee and zonatum too. Just how does one know which one is more interesting/more attractive? (cannot keep them all :( ).

Hi Mike,

the most attractive of the Elassoma spp. certainly is E. okefenokee, due to the larger amount of blue in the finnage.

As far as behaviour/habitus is concerned, the species should be more or less the same.

I'm quite sure you could fit 4 tanks 40x25x25 cm somewhere??? Since they don't need heating or filtration and, if the tanks are fairly close to a window, not even light you could keep them all! Laugh

Shouldn'have said that, now should I. Cool

Regards

Thanks for the recommendation, R!

Nay, 4 more tanks is not an option... too many other interesting creatures around ... :(
Here is the next one for me... incidentally comes from the same waters as Elassoma's. I've been waiting for a while until this strain (subspecies?) shows up again.

I agree with Rüdiger, Mikev. E. okefenokee is the most stunning little fish I ever had. In a way I still regret a bit to have given them to a friend.
