This size kritter keeper holds about three gallons of water. I've found it makes a good hospital tank for ill fish. Its the perfect size so dispensing medications is more cost effective. Plus, you can route in a penn plax smallworld filter (minus carbon, because that takes medication out of the water). Sick fish need aeration, and it works in this small tank.

Never, ever make this kritter keeper a home for goldfish. Contrary to popular belief, goldfish need lots of water to make up for the massive amount of waste they produce. This size would be alright for a betta (who should never have less than a gallon of water, again, contrary to popular belief), maybe a trio of guppies if you have a filter.

This kritter keeper is great, as long as you know how to properly use it.

Although the dimensions say 11.9 x 7.8 x 8.1 inches, the dimensions of the actual plastic tank (not including the cover) are 11 x 6.5 x 6 inches. This is equal to 1.85 gallons. I was expecting a tank that could hold around 3 gallons because I foolishly used the dimensions listed here. I noticed that my tank could hold less than 2 gallons when I was doing a water change and noticed I had only siphoned out 1 gallon of water and the water level was under the halfway point in the tank. Other than that this is a pretty good tank if used temporarily for a sick fish, like I am doing.

I recently bought a second crowntail Betta named Osiris as a next door neighbor for my red veiltail Betta Anubis. At the time, I only had a half gallon bowl to house Osiris. I knew it was only going to be a temporary home for Osiris. As a Betta lover, I would never house my fish in anything less than a gallon permanently. Unfortunately I do not have that much room in my tiny one bedroom apartment myself so I thought the medium Kritter Keeper would be ideal for Osiris. With the addition of blue gravel and a few plastic plants, my Betta is now thriving in his new home. He has lots of room to swim around which is a vast improvement from that dinky plastic bowl I had kept him in, or the plastic cup he was in at the pet store where I bought him. As for changing his water, I never pick up the tank by the handle. It is best to carry it by the tank itself. As someone who lives by herself in a small one bedroom apartment with not a lot of surface space with two male Bettas, I certainly can recommend the Kritter Keeper for people in similiar situations who owns Bettas. Osiris loves his new home. He has already blown a bubble nest in it.

This little acrylic containers are great for bettas. The large is around 3 gallons, and provides a good amount of space for her or him to swim around in. Add some sand and a plant, and your betta will be much happier than in a tiny cup.

Having a lid is great. Bettas can and will jump. FYI - if your betta does jump, he can survive for a surprisingly long time out of water. Put him back in, can't hurt and you might be surprised. He will probably need some stress ease or salt to combat infection. There is an area pre-punched in the lid for removal, if you'd like to add a small filter or heater. If you do daily 10% water changes, you can probably skip the filter (a turkey baster works great for this), but I do recommend a heater if your ambient temperature is lower than high 70's. Bettas come from Thailand, and like water around 80 degrees. If you heat, add a thermometer to monitor please.

Feedback on my reviews is very welcome! Thanks!

I recommend this product for keeping pets that don't gnaw or chew like crickets, small tarantulas, hermit crabs and ,my favorite, walking sticks. I am using the 8 Kritter Keepers I bought to start rare seeds indoors in pots. The clear door between the carry handles allows me to see from the top how my seedlings are doing and work inside the Kritter Keeper. The lids come in 6 colors all of which are bright and cheery. When not in use they can be cleaned and stacked together. I love my Kritter Keepers!

My brother and I have 3 dwarf hamsters and I thought this would be perfect to put them in when I cleaned their cages! I always felt bad putting them into the dark box they came in.. This Kritter Keeper works wonderfully! It's simple, but is big enough to fit their wheel and their little house to hide in. It's also good for transporting hamsters on a trip.

I have owned similar items over many years. These are very expensive where I live and I was happy to find them on Amazon.com for a reasonable price with free shipping. For those unhappy with the cover colors, it does say in the description that colors are "assorted." These are plastic, so one has to take care that they are not dropped or scratched with hard objects. Also the handles are not meant for heavy lifting; these can be easily lifted from their bottoms without the stretch and distortion common to thin-walled plastic containers.

That being said, I received two of these and both have stood up well. The bases are sturdy, despite being filled with water for my bettas. The covers securely snap to the bases. The central opening also snaps securely. I have owned other brands of kritter keepers and the central openings were not secure so that I had to place a heavy objects on the tops to keep my critters from escaping.

My bettas enjoy the space. It's true that bettas can be kept in small containers but they become lethargic and depressed. I "upsized" their swimming area, added a few more floating plants (alas, plastic ones), and they've come to life. I've been rewarded with bettas that swim and strut their glorious fins and colors.
