I know this has been asked many times- by myself also.
But, are Kritter keepers truely worth paying like $15 for large ones?
It seems cheaper, and you do not need a filter, and if you buy a tank kit, you usually end up buying another filter anyway, but, are kritter keepers worth it?
Do they scratch easily? Can you use heaters in them? Filters?
Are they easy to clean?
If you have a Kritter Keeper, can you please post your setup, and how many gallons of water it holds, (About) And how expensive it was?
Hi. I used to keep one of my fish in a kritter keeper. Personally I think they are a good starter tank or if you don't have a lot of money. the L size holds about 3 gallons. They are not the sturdiest tanks and scratch easier however the kritter keeper i had was over 10 years old and worked fine despite the scratches. You can use a heater. I have a 50watt heater and a 25watt heater in the tank over the time I had it and never had any issues. You can have a filter on it. I would suggest either a HOB (hand on back) or sponge filter. I personally didn't have a filter in my kritter keeper but i know of people how have used it
Personally I do think they are worth the money because if you look at those small 1/4 gallon tanks for bettas that petco tries to sell, the kritter keeper is about the same price. They are listed as $13 where I live.
Heres a photo of my old set up before I replaced the tank.
25w. The wattage was recommended by another user, although I took an employee's advice about which brand to buy. Can't remember what it is off the top of my head, but it has adjustable temperature with a visible thermostat.
You'll still need a thermometer, however, to be sure that the settings are accurate and monitor the temperature of your tank.
EDIT: The heater cost $17, the thermometer cost $3. TOTALLY NECESSARY. Mr. Kitty went through a HUGE color and behavior change when his water warmed up. He turned an absurdly dark navy blue, and now he's jumping at food. It's clear that he's much happier. I felt like dirt that I hadn't taken care of that earlier, but I didn't know.
