I hope not; they are excellent pictures which I am enjoying a lot.

I think your rift lake Synodontis could actually be a hybrid. https://www.planetcatfish.com/shaneswor ... cle_id=269
They look a lot like the third photo in this article and don't match any of the Tanganyikan species imo.

Glad you made it through relatively unscathed but sorry for those losses and fingers crossed the large barb continues to improve.

The second one is a species of Gerris. In the UK it would be Gerris lacustris but I am not sure of the species native to California (or the US).

Think I might have found it,

Mesovelia - or Water Treader

The bottom one is only a nymph stage, not a full adult, as it doesn't have wings yet. (They are good fliers when adult.)

The first is a different species as the legs are arranged differently. Where are you from Eric as it may not be a UK species that I am familiar with.

Sorry but they are not Water Boatmen. The top one I'm not sure of the species but the second is a Pond Skater.

Water boatmen (both Lesser and Greater) rest under the water's surface, not on top.

It might be easier to but a product sold specifically for this task?

It says a 4x dose will euthanise a fish.

I have used MS 222 to anaesthetise koi but not euthanise them.

Have you thought about rubber root membranes? The sort of stuff used for bamboo root barriers?

Though I think you might best getting the fish and water out and pouring concrete or fibreglassing the inside. Short term pain but a better long term, robust solution.

I've got a couple of 2 foot tanks on a plastic trim with a floating base and they have been great tanks for 30 plus years. I would assume there's a maximum size where this design would be advisable though. Test fill it outside and leave it full for a while if you have any doubts!

Very true - I've even seen LFS staff do it as a bycatch appears with one lot of fish and it gets transferred to another tank where it looks a bit more like the species being officially sold.

Was just making the point that if it was truly bycatch it can't be the African species.

If it's truly bycatch then it'd have to be a big net to catch both at the same time...

(Kryptopterus and allies are Asian whereas the species mentioned are African)

Could it not be another Asian species? Or it's a mix-up at a wholesalers near to the point of sale of course rather than true bycatch.

Saw three spam posts this morning and clicked the exclamation mark button to report but got an Error 404 message saying the forum report page can't be found.

According to the profile on here they like water from 17oC to 28oC. I think I saw similar temperatures on ScotCat as well. They are certainly nice and active in their quarantine tank at this temperature as I type. There's a decent current in my main tank for the Opsarius and barbs in there but the ...

I've just bought some Scleromystax barbatus and Megalechis thoracata for my cool tank to go with some albino ancistrus in there already.
At this time of year the tank runs at 18oC.

Couldn't find a better place to put this. Heard about this but never had it happen, even in high-tech planted tanks, but today I found a flower finally opened on one of my Anubias 'Coffeifolia' in my soft water tank.

Quite often fish will attack a lure as a territorial response, not just for feeding which could be the case here.

I added k1 to this seaclear uniquarium to get a moving bed filter. Any advice friends. I'm going through old threads so you may have solved this now but I can't tell whether the photo shows your chamber overfilled with media or just with new K1 that does take a while to get 'waterlogged' and ...

First advice would be to keep the chamber as clear as possible and use air to circulate the K1. Nothing seems to fluidise it as well as a good rising air stream that moves the K1 away from the water exit. PXL_20240127_215342718.jpg This is my K1 chamber. Water enters rear right and leaves over the ...

Thanks very much. Will get on with some pectoral fin ray counting to determine exactly which fish is which species.

Thanks Kryptic - does that include the darker individual? I haven't seen any photos of grandiops/multipunctatus that look that dark.

Had a slightly nagging feeling the last one might have been a hybrid as it didn't seem to match either species exactly.

Thanks for the reply. I definitely think the shoal comprises at least 2 species, possibly as many as 4. There are 5 I think are grandiops (the paler fish in the first set of photos are these fish). There are then two fish which may be grandiops or multipunctatus. I'm trying to get a decent photo of ...

Managed to get a pictured of the other unsure species.
I think it is either a lucipinnis but not 100% sure.

Hi all, My first post and I'm hoping maybe someone can help. I have a group of 9 synos that were all purchased as multipunctatus in two groups from my LFS. I think they are all actually grandiops apart from two fish that were in the first group I purchased (the fish pictured below and another one I ...
