I treated myself to 10 of these lil beauties - Nannostomus mortenthaleri aka Coral Red Pencilfish.

Does anybody have experience with this species? What size do they mature? Any breeding info?

I thought it was one of your posts that I'd seen them. They are great, I love them already. Mine were £8.95 from Coxwell Aquatics :shock:

I think I'm going to get a load of Beckfords for my 125l once I put these into my Nano, much cheaper than the Reds :lol:
 
I've loved Beckfordi's since I first saw them in TGM's 10ft display tank. Really do want to keep some soon. My new LFS has them in quite cheap and it took a lot of effort to resist buying 🙂

Not got the space for them at the moment. Wouldn't be fair to cram them into my 90cm holding tank with it's other inhabitants. I'm hoping to set up an 80x45x45 soon. They should suit the scape I have in mind nicely 🙂

Fair enough. They are great to watch, they move quite similarly to dwarf Cichlids I think, move, stop, move, stop, as opposed to the previous inhabitants my Espei Rasboras, belting it around the tank at 100mph :lol:
 
Hi all,

I know a few people that have bred these. Small tanks around 18x10x10 with simple air fed sponge filters. A must is a good tank cover for this. Use 1 male (normally much more colourfull) to 2 females. All used very soft water (less than 1ºGH) with water filtered through peat moss for a week before adding to the breeding tanks. Feed well with live food such as white worm, drop the temp on water changes. Two of them used wool tied to a cork as a spawning aid, one used a bare aquarium.

You will see eggs on the wool and the bottom of the tank, remove the adults. 2 days later the eggs will hatch, lavea look like small hairs on the glass. Start feeding insuforia a day or two later (not too soon) and lots of water changes. Move to larger food like baby brine shrimp when you think they are ready.

Good luck :thumbup:
I must admit, i am in the middle of having a bit of a breeding push at the moment to pay for some equipment, these and cory adolphi are both little side projects at the moment.

Hi all,
That is pretty much how they've spawned for me as well (the very similar N.marginatus). You can use fine leaved plants or moss as well, and if you want ready made spawning mops TA Aquaculture sell them for about a £1.50 each.

The mops are useful for Tetras, Cories, Killies etc. as well.

The fry are incredibly small, which is why the moss method works quite well as it gives them rotifers etc to have a pick at when they are first active.
