Algae and fry

Do fry need lots of algae, are they ok left in with the adults, 4ft planted tank with 6 brown plecs, a pair are using the cave for breeding i think they are bred a couple of times yet i can see no youngsters now.

They should be fine in your big tank!
I have taken mine out in the cave when they are still eggs and put them and dad in a seperate tank...
The tank doesnt have any algae but they have been thriving on cucumber, peas and algae wafers and I also put in a small bit of crushed flake too...
My second brood are just coming out of the cave now!
When I put my big boy back in my 4ft community tank after he let the fry out of the cave, 1 baby fry got in there with him but the little one has been doing great!

Once the egg sac is completely gone the fry, as tilkifox has said will be quite happy feeding on cucumber and other vegetable matter, they are ravenous eaters at this stage so they should always have access to food. They can be left with the parents and other BN's so long as there are no other fish that could make a meal of them.

Sometimes a pair will just spawn other times you may need to trigger a spawn there is post by Curby HERE that has information about triggering a spawn.

Very true Jim..
Mine are eating me out of house and home

hmm ok, there no other fish in there at the mo, i keep getting tempted though. just got a load of live bloodworm they dont seem to shifting much of them though, di
