How Many At Once?

[TekFish]

I was looking to get 18 Rummynose tetra for my 200l tank but I was wondering how many I should add at a time. I know they are sensitive so I was thinking 10 at one time and then a few weeks later get 8 more, or should I get 6 at a time?

what is the current stocking of the tank?

When adding fish you don't ever want to add more than 50% of the current bioload, so that the filter has time to catch up with the increased waste.

Look at signature.
That's what I put it there for

And in Zoddy's signature it says, "I can not see your signature, please don't refer me to it."

I would go for six at a time with your current stocking.

Oh whoops, I'm stupid!
6 at a time you say, I thought that would probably be the case.
That would be in 3 groups of 6, so how far apart should I get them?
1 week? 2 weeks?

Out of curiosity, having read your signature, why 18000K bulbs?

Oh, and I agree, probably up to 6 at a time for that stocking.

That's just the bulbs that came with the tank.
