OK, so i have a few possible options for breeding BNs, i will try to make this as detailed as possible without it being too confusing...
1: Breeding the BNs in a 6 foot tank and not moving the cave, and using a fry saver to grow the fry big enough to not get eaten by bigger fish, then re-introduce the fry into the tank...
Problems: The BNs need a cold water change to trigger the spawning, would this stress out other fish in the community aquarium. It would be incredibly difficult to catch all the fry for selling, this could stress out the fry, and other fish. May need extra filter that take up room. Breeding may almost ruin the community/display tank look.
2: Breeding in 6 foot tank and moving male to a 125 litre to raise fry.
Problems: Would it be a bit difficult to get the cave from a 6 foot tank, (it is quite high edged). Would it be too difficult to match the water conditions. this also has the water change problem.
3: Breeding and raising fry in 125 litre. This makes extra filters easier to maintain.
Problems: Would the tank be too small. Room for putting the tank. Would have to buy a lot of extra stuff, (bogwood e.t.c, (not too much of a problem))
Please tell me if i may have missed anything out, please add any other options you may think of, hope it is not too much
I would have sponge and extra power filters ready and will also have a fry saver that uses its own pump that uses water from the main tank ready for use.
Thanks, any help appreciated
