L200, but which one?

Post by Rense »

A few months back, L200 changed name, again. But this time they split in in 2 different species, Hemiancistrus subviridis and Baryancistrus demantoides.

Which one is this?

I think it's Hemiancistrus subviridus, cause they don't have the orange in the fins. But the Bary should be a plant eating fish and the Hemiancistrus shouldn't be. Mine do eat plants(a lot, unfortunately), so which one is it?

TIA!

The above animal is Baryancistrus demantoides. The amount and brightness of the orange to yellow tinge on the fins varys greatly.

If they are the same fish you placed in your icon picture, IMO, they are hemiancistrus. The adipose-dorsal gap is a bit large. I assume, though, given the advice already given on the topic, that I'm wrong.

nope, that's just a picture from the internet, because I didn't have a digital camera back then ;) I should change it ;)

edit: done ;)

I do see a difference between these 2:

are these 2 different species or is it the same specie?

The fish on picture 1 has a more elongated head and the first spine in the dorsal fin is more 'curved'.

Hello

My personal opinion - I only see Hemiancistrus Subviridis on your pictures.
No Highfins.

But at every foto, we see the fish from an angle that gives the impression, that the tail is rather big - like the tails on Highfins. But the gaps between adipose/dorsal fin indicate no highfins.

But you can better judge it IRL. Take a look and describe the distance. If no distance or only 1-2 millimetres - it is an Highfin. If almost an centimeter - it's an lowfin.

The true Highfins that I have seen - all show a dorsal extremely high. And a very big good developed tail.

Best regards

Rense,
Line could easily be correct that differences in the angle the photos were taken at are influencing our identifications. Any chance of a side by side photo of the two fish above in a photo tank? That would help a lot.

I will try to take a shot of them side by side, if I took a fairly good picture, i'll post it again.

@Line: I've just watched and the gap is definitely more than the indicated 1 or 2 mm, I guess it's about 7 or 8 mm.

thanx 4 the co-op :)

IMO they are Hemiancistrus, not having preadipose plate joint with dorsal fin:

look here, there are pics:

L128 and Hemiancistrus subviridis are very agressive fish with plants. They can destroy even strong plants like Anubias

ok, that explains it. I couldn't find that in the Cat-eLog, but I knew Baryancistrus is a planteater as well, that's why I first though it should be the B. demantoides.

These fish allow only Vallisneria gigantea in the tank, everything else is food. The Echinodorus had also become food ;)

thanx again :)

Hi

Why don't somebody develope food tasting like Echinodorus :D - would be a great hit :)

Best Regards
Line

PS

Following works great with my L200 :
Vallisneria Spiralis
Echinodorus Bolivianus
Echinodorus Tennelus
Ceratophyllum demersum
Vallisneria Spiralis

Lots of possibilities - just avoid big leaved plants of Echinodorus family

thank you!

I've got V. gigantea in my tank, which they don't eat, and the same goes for the Ceratophyllum demersum. I've also got some E. tennelus, but I also have some Satanoperca which keep digging them out of the sand, but hey, I'll just throw some plants in occasionaly and I'll see which survives ;)

Hi

Because of problems with sand/current - I tried to plant the E. Tenellus in thin pieces of filtermaterial (you know - this black or blue foam stuff :D ?) - and a little sand to cover it all..
Perhaps this could work out with your Satanoperca ?
