I purchased four of these so I can say with confidence that the lighting fixture burns through batteries within a single to two uses at most. And in a very short amount of time, the plastic becomes cloudy so I can’t see my fish anymore.

The light runs on batteries. I wish it would plug in because the batteries obviously run down if you leave the light on. Otherwise very Nice product. Big red loved his new home.

Great size for a betta fish. Easy set up. Looks nice

Now you need to know that I did read the reviews and bought it anyway. Guess what? The reviews were right. Within two days the light went bonkers on me. You can turn it back on and get MAYBE 15 minutes before it goes out again. The little bowl works great for me but don’t expect the light to work

Pero la tapa con las luces de led dejo de encender !!!

La calidad es mediana de acuerdo a su precio, la luz es tenue pero hasta ahí se entiende por si relación calidad precio… sin embargo, la liz dejó de funcionar a los 2 días. Comenzó fallando, se encendía sola, ya no obedecía las secuencias con el botón, de repente dejó de funcionar. Muy malo el módulo de luz. Muy malo

Overall nice fish bowl for my son’s Betta fish that he was asking for Christmas. It was disappointing that the tank light stopped working in less than 4 days. The light is on a timer for either 2, 4 hours or off completely. We only had to set to 2 hours a day and it no longer works. Checked batteries and they are fine. So it’s a fine bowl for a small fish but don’t expect the light to continue to work long term.

Muy buena

Muy bonita. Lo único negativo que le encuentro es que el eliminador para corriente electrica lo tienes que comprar por separado. Usarla con pilas no es una buena opción.

I loved this when I first got it, and I still like it... but the lights don’t last long. And I don’t mean the batteries (which also don’t last long). The whole light system will quit completely within 1 to 3 weeks. I’m basing that on the 30 other reviews saying the same thing. Very cute tank, but don’t buy it for the light.

Se ve muy linda la pecera ideal para niños porque es de acrílico y no se opaca

I have kept various kinds of fish for about 50 years now and have several tanks, ranging from 55 gallons all the way down to this great little globe, which I love. Only recently, while searching the Internet for some smaller nanotanks, I've seen some of the online commentary regarding bowls such as this. I was startled to see that many folks believe they're death traps, but the truth is that any tank, big or small, can be a death trap if you are not attentive to it.I set this one up with a small-sized Lee's round undergravel filter. I could have used an extra-small sponge filter such as a Small World filter instead (and probably should have, as those are easier to maintain.) The gravel I used was from one of my well-aged, cycled tanks, so the beneficial bacteria on which aquarium filtration depends was automatically introduced into the globe. The undergravel filter is powered by a $5.00 non-UL Whisper 10-gallon air pump, dialed back a bit with the included valve. The light hood cover of this bowl features a slot for airlines or heater cords, so it is designed for these accessories-- a big plus! The cover measures about 5-3/4" inches across, so will fit other, larger globes as well. I powered the lights with a mini-USB cable left over from an old cell phone.I always use a combination of living and plastic plants in my tanks. Live plants are a very important aspect of tank filtration, especially in tanks this small. They help consume the nitrates which the bacteria leave behind. This tank has Marimo moss, hornwort and baby tears. All three are doing well with the included light. I also found a nice fallen log decoration here on Amazon which is slightly curved and fits perfectly against the curved side of the bowl to make a lovely cave.To help cycle the bowl further, I then introduced a very, very, VERY small GOLDFISH. Yep, a goldfish! This is one from a brood of feeders I hatched recently. He was not even an inch long at the time and was a perfect fit for the globe. He lived in this tank happily, with no apparent stress, for several weeks, and then I put him in my goldfish pond where he is still living-- and growing bigger. I understand this method of tank cycling is now considered old school, but it has always worked for me.Finally, after all that, I introduced my fancy floofy halfmoon betta into the bowl. He is active and thriving there. He has plenty of room to swim, spaces to hide, and structures to explore. The bowl is on my computer desk right at my elbow, so I interact with him a lot. This lets me keep a close eye on him and the water quality.So far I have had zero problems with this fish bowl or its lights. The plastic (I hesitate to call it 'acrylic') is thin but very clear, with some small imperfections which don't bother me but could irritate folks used to the polished perfection of large acrylic tanks. The multi-colored lights are beautiful and even adequate to grow low-light plants. The lid has a cutout for heater cords and airline tubing. Overall this is a wonderful nano-tank.This one gallon bowl works perfectly for a betta and some small snails, such as the two ram's horns I have in with mine. Many different kinds of nanofish fry, such as guppy fry, would also find this bowl an excellent home, as would a few cherry shrimp. A tiny baby goldfish can be kept in here for a little while as I did, but not permanently. With all aquariums, it's important to do a partial water change once a week.Bottom line-- add a filter and don't overstock, and this little nano-bowl will work fine and really look beautiful.
