Quick tropical fish questions

[anonymous-user]

Around 2 months ago we got our youngest son a 70l tank and maybe 10 fish.

We noticed a few fry knocking around soon after and left them but they all got eaten.

So, this time we have fitted a nursery tank and transferred 7 fry into it. Ive got some questions if some helpful types can help?




Ive added some gravel to the bottom as a noticed a couple escaped through the slits

1 - Is it OK to have the gravel in?
2 - How do I keep them in there for?
3 - Do I feed them? If so how; with the same food as the main tank?
4 - Do I need to change the water in the nursery tank?
5 - I noticed after a day, looking up from the underside of the nursery, there is a light film of algae on the top of the water in the nursery tank - should I leave it?

Any answer would be appreciated and any other tips too!

1- as long as water can still flow in and out then that's fine.

2- let them out when they are big enough to not get sucked into the filter.

3- newly hatched brine shrimp (sea monkeys), self farmed copepods (I think) or what I do is a tiny amount of finely ground flake food.

4- see no. 1

5- I would remove it as it could affect the oxygen exchange of the water surface.

Not expert answers by any means but has worked for me in the past.

What ransoman says is what I've done in the past, although without the gravel

Did regularly have a few of the bigger fish jump into the tank and start hoovering the fry however...

Thanks for the replies - appreciated.

I've checked and there are slits in the side of the box so water can flow through.
It comes with a lid too so no jumping fish!
I'll keep them clean watered by tipping the surface layer of water off each day too.

Thanks again

Finely ground up with your fingers flake fish food works for me.
I have Endler's guppies in a mixed community tank - nothing interested in eating them - and their offspring do just fine.

My platys never stop breeding, I wish some of the other fish would eat them! We had five to start with and there must be 20 fry and juvies now

Thanks for the input.

The fry (8 off) are managing quite well in their little nursery. I've been grinding up regular food into a powder and they are scoffing it up
