I'd like to store my goldies in a plastic container with a lid (temporarily for moving, and perhaps medicating), and was wondering if this is safe, since these containers are sold in non-fish stores (I've seen lots of those storage boxes that comes with rollers, they look perfect for storing fish, to me). As most of these things are coloured and bulk made, is it possible for the container to contain chemicals toxic to fish? I suppose this question can apply to pails/buckets if I intend to leave fish in for a long period. Most new buckets come with a suspicious smell

Use some vinegar or bleech if you prefer, and wash it out VERY thoroughly(sp) and you should be fine, I'm guessing your talking about RubberMaid type tubs, the only thing I'd be careful with is those are usually made to hold, clothes, shoes, papers not 8 lbs per gallon of water, so becareful when moving and also watch for leaks when full..thats about all I can say..have fun

Can I ask y u need 2 "store" ur fish?

perhaps the term storing was not entirely appropriate I want to put my fishies in a container with a lid for moving to another house, and since I'm having some parasite problems, would like to be able to treat them in this container (since it's rectangular shaped, feels better than storing them in a bucket which is usually not see-through), while I wait for the main tank to starve the parasites Hope this will work though....

Hi Kat, I'm using one of those plastic storage tanks (with a hang-on filter) as a temporary tank.

It did have a funny smell for the first couple of days but I just kept changing 50% of the water until the smell went away. It hasn't effected the fish, they quite like it.

Thanks Annette, good to know others use this too Most of these stackable storage things comes with roller wheels - I do hope they can hold the water weight

Yeah, i'd go for the clear plastic ones (i don't know how long it is good to keep the lid on for though) and when you get them to the new house, hook up a filter on to it.....and do wash it out good first, and perhaps set it out in the sun for a day before putting fish in it...sun is good at killing smells and such.
and yes, those containers are usually recommended for people who have a small overstocked tank and can't afford a bigger glass aquarium!
-good luck!:)

The reason why I'm still hesitant about plastic storage boxes is (as a QT): temperature concerns - I don't think I can put a heater in plastic will melt. Oh, also I am not sure if it's ok to put 5 fish (3 small 2 medium) in a single box. Is this acceptable assuming that I aerate vigorously, and change water everyday (or move to a new bucket of water every 2 or 3 days as I treat with Prazi say)??

I finally got 2 of this rectangular shaped plastic container (hobby storage box, usually for putting tools and stuff...non food grade?). I have tried rinsing them with warm water and realised they feel a bit "shiny"...water not adhering to it like a normal pail/bucket. The last thing I want to do is introduce my fishes from parasites to toxic chemicals. Anyone has experience with this? I'm going to repeat this post (about "constant parasite problems") in the diseases section, to get advice on this. For instance, will it react with Praziquantel, heat or especially Potassium permanganate?

Thanks
