Lovefish Concept 27 Litre Tank

So I've just bought this tank as I need to take out my baby Kribs from my main community tank. My concern is that the built-in filter, while not powerful in its flow, could be big enough for the babies to enter.

May be a long shot but is there a way around this without having to change to a different filter?

It's split in to compartments. First compartment is left empty (not sure what for). Second compartment features a sponge pad, carbon and another sponge pad, third has a sponge pad followed by other filter media and another sponge. Final compartment is where the pump is situated and the outlet/pipe for that fits through a slot to then enter the tank. It's the outlet pipe (probably not the proper name but it's late that concerns me.

I did buy a sponge filter, just not entirely sure how it works. This is the one I bought: http://www.amazon.co.uk/Single-Sponge-Filter-Aquarium-breeding/dp/B00ALYRXIW/ref=sr_1_1?ie=UTF8&qid=1422788495&sr=8-1&keywords=single+mini+sponge+filter#productDetails

Do you know how it would connect to an air pump?

Will do. Failing that, do you have any recommendations on a suitable sponge filter?

Thanks Sanjo, got it all connected and that is what's happening, although it is slightly noisy.

Air pump is fine, just a gentle hum, it sounds more like the water going through the filter isn't running through smooth, but maybe I'm just not used to it and am being fussy

Do you mean out of the first tank bferg4?

PS I have two air pumps on the go at present and one of those is VERY noisy.
Shouldn't complain though as it was given to me in the 1st place and I have repaired it so shouldn't expect too much.

Moved some of the fry into new tank. Not moving them all as I don't want to risk losing them all. Easier catching them and moving them than I thought it would be (used the jug and net method).

Cloudiness isn't usually harmful. If it is from the sand, it will slowly settle out. Or it could be a bacterial bloom. Bacterial blooms are only harmful if the bacteria use too much oxygen from the water and deprive the fish. If the new tank and the equipment in it are brand new there could be a fair amount of plasticiser and chemicals from the sealant feeding the bloom bacteria. And any uneaten food from feeding the fry since they went in the tank (though it is probably a bit quick for food to cause a bacterial bloom)

The ornament would have had some bacteria on it; checking the levels of ammonia and nitrite for a few days will confirm whether it has enough for 2 fry. Because they are growing rapidly they do produce more ammonia than you'd expect for their size.
The water from the main tank wouldn't have had any useful bacteria but would have meant the water in the new tank would be similar to the old.

The two baby kribs that I moved to into this tank sadly died. I had tested my water last night and all ok, arrived home from work and they were lying on the bottom. There is uneaten food in the tank from when I fed them last night, and with no algae source like there is in my main tank I'm wondering if they have starved? Or perhaps they have been too stressed from the move over? Any suggestions on what may have happened and how to prevent it are very much welcomed.

Thanks.
