Moving Fish How Many At A Time.

[dave_m13]

Hi All

I have a quick question I am due to be moving most of my fish in the small tank into the larger one and was wondering how many could be moved at one time.

Thanks
Dave

First off how big is the new tank to the old one? Since you're asking I'll guess it's a new set up. If the tank were twice as large as the current one then I'd transfer everything in to the new tank (gravel, water, rocks everything) it'll be like doing 50% water change. I'd bucket the fish then move as much as you can with the water to the new tank. Then I'd get a collander and move all the gravel and set the tank up nice. Then add the fish and clean out the stinky old tank .

If the new tank is larger than the old tank by 2 (20 gallon to say a 55 gallon) I'd pretty much do the same but not fill the remander of the water to 55 gallons. 20 gallons old water and I'd add 20 New water and leave the 15 gallons out. That is if the system can run that way if not add the 15 gallons and watch the water for an ammonia spike.

I would be comfortable doing 50% water change (with extra circulation to airate the water) but that's just me.

Doesn't seem so, check the sig

I'd say...
Week-
1-
5 shrimp and 2 otos
2-
All 4 loaches
3-
8 cardinals
4-
7 cardinals, 1 ram

Obviously that's assuming you're moving everything over, which you're not, so adjust accordingly.

Thanks OohFeeshy that helps.

They will be put into the larger tank, getting another filter for the larger tank so should be ok regarding stocking, also they are all pretty small and do not create all that much waste.

Do not have time to look after the 2 tanks, so one had to go but do not want to sell or give lfs the fish so I thought i'd add them to larger tank.

Do you think I may get away with doing it in 3 weeks?

You could add them all at once if you moved over the filter from the smaller tank at the same time.

Its actually going to be a new bigger filter, probably 2-3 times bigger. Will that make a difference to biological load?

Thanks
