The aquarium comes with everything you need to start your new hobby, including an acrylic tank, low-voltage air pump, white LED lighting, filtration, and instructions.

Fun Little Tank
Fun little acrylic fish tank. The bowl type shale makes it really unique to look at and throws off the perspective of what’s inside. A little too small for most fish, but some small shrimp or maybe even micro crabs would do wonderful in here. I have mine planted with aquasoil and some easy to grow plants. The LED light is plenty for basic plants.The filter also works well, but be warned it’s on the same outlet as the light, so you can’t use a timer without having the filter go off at night. This is actually how I have mine set up as I don’t have any fish/critters in the tank right now.I’d definitely recommend getting it while on sale, because the price is a little steep at full price

Beautiful fish tank
I love this tank. I always get compliments on it. We’ve had it 2 years, going on 3. Literally everyone that has already seen it, comments on it every time they come over. We will catch ourselves staring at it for a long time lol. I have the 8 gallon and it’s pretty big, has its own sort of presence in the room. The price is kind of more than I originally wanted to pay, but I think it’s totally worth it. Cleaning it is not my favorite thing, but that goes with any tank. I wasn’t sure if it would hold up because it’s not glass, but it’s very sturdy. It’s heavy enough when it’s full, so I’m glad it’s not glass after all.

Fish killer. Doesn’t keep clean.
Kills fish. 2 times fish just disappear. Filter too strong. Gets extremely dirty and full of algae very fast. Not my first tank, but my first and last biOrb. Very pretty but a waste of money.

Nice Design
It’s a beautiful orb tank. Easy to care for. My daughter’s Betta loves it. We purchased a fan and placed it above the tank. Because of its orb design, it traps heat easily. It’s in a room with good ventilation. Near a window but sunlight does not touch it.

Worth the Money – Long As You Set It Up Right
Meets every expectation! Most beautiful aquarium I’ve ever owned!NOTE – I have 20+ years experience keeping fish. But after reading so many negative comments (most of which are on the silver MCR-light version), just to make sure, I talked with my local fish store equipment experts to make sure the little guys in my current tank would transition ok to this new tank, before I even bought it.Here’s my advice: Regardless, buy the air stream cap!! It’s only $2, & it will make sure nobody gets stuck in that tube! (See newer pic with assassin snail).-If this is a brand new aquarium for you, I would set it up according to the instructions. *Yes the air pump will be loud if it’s right next to the surface the tank is on, as it vibrates. I recommend putting the BiOrb on a cabinet/stand with a drawer/shelf inside that you can put the air pump in (with a hole in the back for the tube to connect through).*Keep in mind most tropical fish need a heater (yes the tank lid has space for its chord), so I would buy one. If you don’t want to buy any decor not sold by BiOrb (like live plants & wood), you’ll need to start slowly with your fish. I would add any bottom feeders (shrimp, snails, ottos) on the 1st day that you can add fish, & NOTHING else. (BiOrb DOES NOT recommend corys with their pebbles just FYI.) Wait another 2-3 more days, then add your other fish. Stay away from micro breeds & any digging breeds (again due to their pebbles) and don’t overload the tank. The general rule is 1 inch of fish = 1 gallon of water. This model is an 8-gal tank, so no more than 8 fish total. Again, talking with your fish store expert will help. If everyone’s happy in 8 months, you can be more flexible with this.-If you are transitioning fish from an old tank to this one, this will work great. Don’t use the fake pebbles that come with the tank if you’re fish are smaller than 2″. These pebbles are large & oddly shaped (& this is why small fish get stuck in the filter). Use standard, large aquarium gravel, or river rocks as I have here. The goal is to cover the filter enough that no one will get caught inside, but there will still be flow. Sand is a no-no as it will get stuck in the filter. If you use substrate, you’ll want to use it in combination with something else, & position it away from the filter. You might need a bottom feeder fish if you don’t have any, &/or don’t want to clean the tank with a gravel vac as the filter will work slightly slower with smaller gravel just FYI. As my picture shows, I’ve already moved all my rocks, wood & live plants to the new tank right away. I recommend this (your fish will be fine without decor for the 3-day period the BiOrb needs lol). This will establish the healthy biome faster, & prevent ammonia spikes when the fish are moved over. If you have a planted aquarium, I would move some, but not all, of that so neither tank’s biome gets messed up. Also, I’m not using the water bio booster (that comes with) because I have live stuff already in the tank, again to prevent ammonia spikes. And I have my own water conditioner my fish like, so I’m also not using the one that comes with it.Hope this calms some nerves! This really is a beautiful aquarium, my fish will love it!!——-Update 2/23: Still love, love, love this aquarium! It took a few months to get the ideal balance between fish, decor placement, & cleaning (this is an 8 gallon, my previous tank size for over a decade was 5 & a completely different shape/setup)… But I expected that. Currently it has: Cardinals, a couple danios & platies, a licorice gourami, that snail, & two amano shrimp (one of which is preggers, so yeah everyone is pretty happy lol).

Beautiful but challenging.
I love the look when I ordered this tank. Easy setup but trying to catch the fish was harder then I thought. The shape makes it hard to see them and the net doesn’t fit next to the wall and the fish slip past it. Also the small opening doesn’t help. There is not a lot of floor space either making it tough to decorate. The treasure chest and log tunnel sit lopsided. I am going back to a rectangular tank. It looks very nice but I got this for my 5 and 7 year old grandsons so I could teach them the joys of a fish tank in the house and the responsibilities of taking care of it but this one is a bit too frustrating and I fear it might scare them away from those joys. It is beautiful though.

Très bel aquarium mais le bruit de la pompe est insoutenable. Si quelqu’un peut me donner un modèle similaire de pompe, sachant que la lumière y est aussi raccordée, SILENCIEUX !!! Merci d’avance :))

A prima vista bellissimo, a parte il colore inviato errato, nero anziché argento, speriamo duri nel tempo.Soddisfatta anche dal fatto che Amazon mi ha applicato uno sconto per la consegna del colore errato

Tolles Aquarium, viel weniger Algenbildung als in herkömmlichen viereckigen Glasaquarium!
