Darkness' fish - Page 9

Watching them you certainly see why they've become such a sucessful fish, adapting to fill all the niches they can. The extra investment they make in protecting the young definitely pays off for them, mine manage to breed successfully when everything else that tries just gets eaten.

Saturday I took all of the rocks out of the tank to try and catch a pair of pregnant females and a half dozen kids around half an inch big...

Of course after I removed the rocks there were more than 6 kids, but I caught them all and the pregnant C. afra and A. sp. Lwanda. They are now in the breeding tank. I put back te rocks again, so the tank looks a bit different now.

Then, last night, both the L. caeruleus and the P. scolofi started spawning... The L. caeruleus is very small still. Too small to carry to term, IMHO, but we'll see what happens with the Scolofi...

I'm running out of tanks to move the pregnant females and babies to...

Don't fish just lay eggs and then leave them in peace ?
What is this talk of pregnant fish ???

Tubby Rower · 22-05-2007, 20:00

Some fish spawn live fry... some fish lay eggs and leave them.. . others lay eggs and guard them.. and these lay eggs and keep them in their mouths until they hatch and then keep the fry (baby fish until they are big enough to be kicked out.

Yes, it's fascinating watching the parents taking care of the young, they'll take them in a little group around the tank to find food and I've even seen them bringing food to the youngsters. Any other fish that dare approach will get chased off, even if they're much larger!

Like Furiey and Tubby said, fish species have different ways of breeding. Mine are mostly mouthbrooders. Which means that after the mating, when the eggs are fertilized the female takes the eggs into her mouth and starts breeding them for 3-4 weeks. So, she's "pregnant" then...

Both the scolofi and the caeruleus female ate yesterday, which means they swallowed the eggs...

Better luck next time...

OK, big change coming up...

I've been considering this for quite a while now, but while I love the bright colours that my Malawi's have, their behaviour doesn't compare to the Tanganyikans that I had before. So, after considering this carefully for the past two weeks, I have decided to go back to Tanganyikans...
