How to float quarantine container in tank?

[FishyWishy]

Hello,

Our poor boy is sick. He's lethargic, has reduced appetite and now a popeye. :( Someone said to float a small tupperware container in his tank and do daily water changes. This may be a silly question, but how exactly do you do that? When we put a tupperware container in the tank, about 2/3 full, it tips over, fills with water and sinks. Surely we are missing something here?!

Thanks!

Ive always wondered this too!

I put the fish in the cup, put clear wrap over the top, poke a few holes then use a couple clothespins on the side. Im actually wondering how others do it, i watched a video of someone "floating" their fish and they just put it in a cup with a lid and the cup floated but..mine didnt do that XD

I always use the cups we get them in at the pet stores. they float fairly well. I've never had any tip over or fill up on me, but my sister has had the bad luck of it happening once or twice. We caught it in time and no bettas died thankfully.

I'd just suggest using the cups from the store and putting the lids back on.

Thats what i attempted and failed :)) Maybe im putting too much water in the qt cup.

I usually fill it 3/4 of the way up with the fish in it. How much were you putting in? It might also help that my cups catch on the light in my aquarium hood and that keeps them pretty stable.

Id say 3/4 also, i tried different sized cups since i bought from three different stores, itd float, then lean, then turn sideways and water would start to come in, clothes hangers help alot though, but then i worry about a jumper, but if they are sick enough to need their cup they usually arent jumping i guess.

I'll wrap a rubber band around the container, then fold another rubber band in half around the first one and wedge the second one under the lid, lol

masking tape also is a magical tool.....
