I just went out and got a big plastic tank it can be used for fish, reptiles etc, my intentions were for baby fish or to use it as a hospital tank, but Im told i cannot put a heater in it as its plastic So how do i go about putting in my ill guppy? Do i need to have a filter running and is there NO way i can put a heater in???
I was told that as long as the heater doesn't touch the plastic, then it will be ok. Never tried it though.
And yes, you will need a filter. A sponge filter will do even.
I have plastic 4 gallon which has a heater. as long as it doesnt touch the sides then its ok. the suction cups give it the clearance needed but try and find a short one.
how many gallons is yours? if its around four then a simple air driven filter either a box filter or sponge filter would work but a very small internal will be more effective and if the current is too fast then place a tall ornament or plastic plants in front to break the current.
I've got a 1.5 gallon plastic kritter keeper that I have a betta in and I've got a heater in it and it's fine. Like everyone else has said the as long as it doesnt actually touch the plastic it should be ok.
