Hello Yann,
Funny, because I realized I meant to write Peckoltia L168 not L69 and came back on line to edit my mistake.
Not a rare or expensive species but maybe good to practice on. I just finsished with my L134 fry hunt and came up with about 50 fry and the breeders appear to be on other spawns.
The more I think about a loosely organized species maintenance program the more I like the idea. As a group, we have bred many Hypancistrus and trading juveniles for other species among breeders makes a lot of sense. I already am trading some L134 for some TR L201. I say L201 because these are not either H. inspector nor H. contradens according to the breeder who's fish were identified by Ingo Seidel. Apparently there are several species that resemble each other. Now, isn't that a surprise.
This problem has been like the unacknowledged elephant in the room for a long time. There is no reason why we can't develop tank raised strains of popular Hypancistrus spp like L66, L260, L333 and many others.
I don't mean to sound elitist, but the practice of buying one of every pleco is really a dead end and should not be practiced. If H. zebra can be cultured then so can any of the others. They may not be the easiest tropical fish to breed but then again, they are not difficult compared to true Symphysodon discus or Pterophyllum altum either.
It is a surmountable challenge worthy of pursuing seriously. I know that many other hobbyists have been working on culturing Hypancistrus and that enough are succeeding to achieve developing larger aquarium populations.
I have been combining the culture of colorful fresh water tropical shrimp in my pleco breeding set ups and it has been working out well. Neither animal interferes with the breeding of the other nor harming the young. The shrimps add a lot of interest to what otherwise can be an apparently empty aquarium.
Barbie and I have often discussed how important patience is to breeding plecos. I'm finding that raising both together really helps me be more patient with the plecos since their first spawns are so often not completely expected or planned. Especially at first. I'm up to five species of shrimp coexisting and breeding with my plecos. My point is just that breeding plecos can be combined with the shrimp which are becoming very popular and help fill in the time and make use of sometimes unproductive tank space.
