Using diff. sized-plastic storage containers, to house & raise fish

I am wondering if anyone else here is doing this cost-cutting
activity, or if anyone has any advice or comments that they would like
to share about this. Currently I am using several inexpensive plastic
storage containers,...In the smaller one gallon shoe-box type containers
that I have, are 11 of the 14 Betta splendens, or Siamese Fighting fish
that I have, with the other three Bettas living in either my #1 [30
gallon] or #2 [20 gallon] glass tank, or in the one gallon isolation
tank. The next larger plastic container, Tank#3, is the one that holds
13 =BD gallons, and is currently home to a bunch of very pregnant Fancy
Guppys. Then I have Tank#4, a plastic storage container that is 25
inches long, by 15=BD inches wide, by 5=BD deep, where my Platies are
now living. In Tank #6, a 4 foot long, by 3=BD foot wide, by 5 inch deep
plastic container, is now home to all of my 20+ baby Fancy Guppys and 4
adult Fancy Guppy females, not currently [looking] pregnant, and one
very small Pleco [2=BDinches long]. I have that container sitting atop
of a 4=BD tall, 3 foot wide bookcase, and it really has the feel of a
small pond, especially with some well-placed stones and several bunches
of emerald green Elodea densa aquatic plants, which helps to keep the
critters within, both a whole lot healthier, and feeling pretty secure.
I highly recommend that if you have the type of space and location
needed, that you consider trying to create a similar sort of a
'mini-pond' like this one, especially if you have a wide book case or
other secure location to place it on, closer to eye level, were you
don't have to bend way over to look at it.

Elodea densa plants in my other larger plastic containers and aquariums
as well.
=A0=A0=A0=A0=A0=A0I don't know how much the two larger containers cost,
because I traded for them. But I purchased both the one gallon plastic
containers that only cost me .99=A2 each, and the 13=BD gallon
container, which only cost me $6.99 each at a Walgreens department
store. And where you can only clearly see your critters by looking down
into each tank, the containers are great if you are short of cash, and
they seem to be okay health-wise for the creatures living in them. Pax
