What do you plan to keep in it? If it's a betta, or African Dwarf Frogs, I have a suggestion that isn't fancy, but is inexpensive and works very well.
I keep my ADFs in a one gallon mayonnaise jar that I got free from a deli. While many products now come in plastic containers, some still come in glass. I've seen gallon jars of pickles in Walmart that cost less than a one gallon plain glass tank would cost.
The added benefit is that they come with a lid, in case you want to keep the inhabitant (s) from jumping out.
yeah weekly water canges keep mine in good order i always refill it with water out of my 130L tank. it's empty at the moment tho!! did have two mollys and a very small plec in it.
i just want to keep plants in it no fishes
to make something like this
i was going to buy it but i thoulth y not make 1 4 cheaper ( that little thing costs £120.00 for the glass version and £85.00 for the acrylic version )
