L200 Hemi or Bary

[PlecoCrazy]

I have three L200's that I pretty much think I know which and what sex but want to make sure. If you could please let me know whether these are Hemiancistrus or Baryancistrus plus what you believe the sex is I'd appreciate it. Thanks.

Hi,

these are Hemiancistrus subviridis, easily seen through the lack of a membrane connecting dorsal and adipose fin.
I´ll leave the sex determination to others, though.

Cheers, Sandor

Im no expert, but if I were to call any of them female it would be fish #2. Just my 2¢ guess

Fish 2 does look a bit fattier, but I'd say it's unlikely to be female based on other body features. However, these are not easy to sex, at least not when they are less than 4" SL - and these look to be about 3.5" TL, so have another inch or so to grow before they are "teenagers" - and they should reach about 6-7" TL.

Hi Sandor
although I clearly agree on the statement that these are Hemiancistrus, be careful with your suggestion on the mebrane connecting dorsal and adipose fin.

As you can see on my webpage (http://www.nature2aqua.de/BilderSeiten/ ... /index.php) I have both species, but there was one individual in an import box from Columbia, which is definetly a Baryancistrus (confirmed by Harvard) that lacks the mebrane connecting dorsal and adipose fin. I'm quite shure that this individual had this missing membrane also some months ago, when I got it from Columbia, a box of 20 L200 which I sorted late at night only relying on this membrane to distuinguish between High and LowFin. And normally it is to expect that such parts of the fins are reapired within a few weeks, if it depend on a damage. Thus, this must be a malformation!.

I would suggest, as always quoted by Harvard, to check in addition the dots on the dorsal fin (Hemiancistrus on the spines, Baryancistrus between the spines) and the pelvic fin (Hemiancistrus without, Baryancistrus with dots).

Greetings and a Happy New Year to all

That's a great piece of info. I hadn't read that. I think I have one individual with the condition you described where the membrane was damaged, but the general colouration and finnage was wrong for a

Hemiancistrus subviridis

. I'll have a close look today when the lights come on to confirm the spots.

All three are Hemaiancistrus. The spots on the softrays of the dorsal fins leaves no doubt.

The fish are not that big yet, but I think fish 1 and 2 might be females and 3 a male.
