No, the feeder fish carry many diseases.AquariumLover;1266395; said:seed the tank? well i was going to add some feeder fish to the tank to see how they handle it. and then by how they act and the water parameters, start adding other fish.

fsc46;1269283; said:I usually...
fill the new tank with tap water
dechlorinate the water
turn on my new filter without any filtering media for a day or two
take the new media and drop it into the old tank next to an air stone.
match the temp in the new tank with the current tank
Day 3:
make sure the temps match.
add a plastic bowl filled with gravel from the old tank under the intake of the new filter when I add the sponges.
after adding the bowl I'll move some/ all the fish.
feed very very lightly for the first two weeks and check the ammonia, nitrite, nitrate levels every day.
when all the fish are out of the old tank move the filters with them to the new tank.
there is more and I can add it later, but this hopefully gives you some ideas you can use.
kay-bee;1276812; said:If you move the filter which is on the (fully cycled) 29gal to the 75gal, that tank will be ready to instantly support the fish currently living in the 29gal. Alternatively (if utilizing a different filter on the 75gal) you could tranfer all of the filter media to the new filter (if design permits) to achieve the same results. After which you could incrementally increase the bioload in your tank.
I grew out a bunch of mbuna juvies in a 44gal (dozens of small fish). In a single day I transitioned the fish and the filter to a 75gal with no cycling issues (also added two new filters but they were non-factors in the process).
The danger comes when adding a bioload larger than the one the filter is currently supportiing. If the filter is supporting 6 fish in a 29gal, you would likely see some ammonia/nitrite spikes if you moved the fish and filter to the new tank AND added a dozen more fish (in one day).
