Which fish in what tanks?
You might have read my previous thread (fatal low oxygen emergency), if not, I am currently cycling a 110 litre tank and keeping my fish in other tanks temporarily. The problem is, I need to move my guppy fry as they are disappearing (possibly being eaten) and the larger ones are getting fin nipped. I am not sure how I can safely arrange my fish so the fry are alone?

These are my tank set ups ATM:

64 litre planted tank:
5 white cloud mountain minnows
5 golden mountain minnows
2 cherry barbs
5 small neon tetras
1 bristlenose catfish
numerous guppy fry (various sizes)

30 litre tank:
6 guppies

110 litre tank(couple of plants, more coming soon):
1 balloon molly
1 dalmation molly
1 male betta (in a breeding net)

Obviously this is not ideal and once my large tank has cycled I want to put my betta and neons into the 64 litre, fry in the 30 litre and everyone else in the 110 litre if compatible. But for the time being, how can I save my fry from being eaten/fin nipping and make sure everyone has enough space? I am doing frequent water testing and large water changes.

Aside from moving out the fry, provide hiding places; the best are floating plants. But why not let the fish eat the fry; you will have plenty more, believe me. B.

How far along is the cycling on the 110l? You can probably move the betta in the breeding net to the 30l along with the fry and put the mollies in the 64l for the time being.

Honestly, I'd not put the effort into anything there for the fry. If you have decent amount plants in there, some fry will survive. But these Guppys have so many baby's all the time, you'll have PLENTY more to come in your new set up, so don't worry!

I've only been cycling a few days :( My 64 is already really quite overstocked, and the mollies are quite large. Do you think it is too soon to put the guppies in the 110 so I can move the fry and the betta in the net to the 30?
I will get some floating plants Byron, thank you. I am more worried about the fin nipping then the fry being eaten. Also, I have noticed at least a couple of the larger fry with deformed(?) tails, in that they kind of go to a point rather than fanning out, I am not a fan of 'culling' fish but I don't want them to breed obviously, is there anything I can do short of getting yet more tanks and separating them? How old must guppies be before they can breed?

Did you have any ammonia or NO peak's at all yet?
Is the 110l seeded by another tank?
Have a bunch plants in there?

Apart from separating all F/M amongst your livebearers there ain't much you can do to avoid a bunch fry all the time.
