Could these guys be L27 goldline/thunder?

I don't think they are 'Thunders' although I'm not too sure what qualifies as one. The fish on the right and the second pic looks like a and the other looks like it could be the same but maybe . Either way they are beautiful fish, my favourites.

The asians call them thunder pelcos because the yellow lines look like lightning.

But from what i understand, the thunder pleco is actually an independent species?

They are beautifual as small, but lose their colour with age... Just look at that long nose.

I don't think that 'Thunders' constitute a new species, just another variant. A lot of the Brazilian river varieties are essentially the same and resemble Panaque nigrolineatus, there are only a few small features to differentiate. But 'Thunders' definitely have longer noses like you say. I don't what river they come from, the second picture I recognise from Rayon Vert Aqua and supposedly comes from the Rio Teles Pires and I haven't seen another like it. To add to the confusion I learnt from Janne that Rio Araguaia Royals (from the Cat-elog) are actually from the Rio Teles Pires (upstream of the Rio Tapajos).

Whilst planet catfish often puts regional varieties as "species" in the Cat-eLog, only fish that are scientifically described can be clearly said to be "a new species". However, for breeding purposes, different regional varieties should be kept apart, whether they are scientifically considered the same species or not.

The big panaque is the same type as the smaller one under it. I got the picture from our exporter in brazil.

He says that they lose their colour with age. Also, the pic of the smaller panaque has been edited to look more shiny and golden.

Yes, they are thunders (or "God of Thunders") as the head shape is much elongated and different from L27C (the usual gold-strip)... As a remark, this name should originally come from Japan...

...He says that they lose their colour with age...

Does this mean the stripe will fade to the solid overall dark coloration of the body?
