What will happen if i move 3 Danios and a Glolight tetra into a new tank after 3 days of setting it up?

Question

Will they die? If so why? Sensible answers only please!

Answer 1

Move the filter and some of the old substrate with them and you should have no problem (even if you leave the old substrate in the legs of an old pair of nylons for a week and leave the old filter running for only a few days). If you don't 'seed' the new tank with the nitrifying bacteria of the old tank the spikes of nitrites, ammonia and nitrates in the new tank will poison the fish.

Most members of the Danio family are extremely tough. You could probably transfer them with no problem. With Tetras however, you should be more careful. After 3 days any chlorine you might have in your water , if it's city water, would have evaporated. You don't have to worry about cycling, that's only if you are dealing with African Cichlids or salt water fish. If you are moving them from another tank, take say 1/4 of the water from the old tank and put it in the new tank. The following is most important, and is all I would do in this situation. Make sure the PH is the same. If the water temp. is the same,then you can put them in. If not, float them until equal. The only reason for the other precautions above is I knew you were very concerned, and I wanted to make sure things would go right

Answer 3

Well - I don't know how large your tank is, but if it were me I wouldn't put any fish into a tank that wasn't cycled first.

If you put those fish in that tank now the only thing that is going to happen is that they will start the Nitrogen Cycle with their waste, and that is going to start the whole Ammonia to Nitrite to Nitrate process, but doing that with fish could take from 3 weeks to 2 or 3 months depending on the size of the tank.

Might I make a suggestion for you when setting up a new tank? Do what's called a "Fishless Cycle". Here is one of the best articles to date on how to do just that (read the 10 and 14 day recipies when you get done reading the main body of info)...

Good luck to you

Answer 4

Use 1/2 of the old water in the new tank, if you can. Use the same gravel, decorations, filter if you can also. All of your beneficial bacteria will be on those items in some amount or other. If you're using a new filter, just hook the old filter on to the new tank for about a month or so(with the new one on also), that'll help kick start the new filter bacteria growth. This will prevent the tank from cycling and harming/killing the fish. Be sure to dechlorinate the fresh water added to the tank. Also, adjust them to the new tank water slowly. Maybe try putting them in a bucket with some of the old tank water, slowly add small amounts of the new water to the bucket. This will adjust them to the ph and temperature changes.

Answer 5

Ok, so ur moving them from one tank to another..... put some of the water that they were in, in your new tank. Depending on the size of the tank the amount will vary. But about 30% should be ok. Also as another person has said, dont put them straight into the water put them in a bag first like when you first get them. leave them for half hour to adjust to the temperature then let em out

Answer 6

the tank needs to be cycled but you can cycle your tank with the fish in them try this it may help good luck!

Answer 7

Go for it the tank is fine and the fish will be too.

Answer 8

NO SHOULD NOT KILL THEM BUT LEAVE THEM IN A POLYTHENE BAG SO THE WATER TEMPERATURE EQUALS THE TANK OR THEY COULD DIE OF SHOCK.
HOPE THIS HELPS

Answer 9

That should be just great that is plenty of time!
