biOrb Classic 15 Acrylic 4-Gallon Aquarium with White LED Lights Modern Compact Tank for Tabletop or Desktop Display, Black-Trimmed Tank

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).

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.

Always wanted one,did my research, got it and I love it. So clear and very quiet . My fish seem happy and it's so relaxing to watch.

I got this because I wanted my goldfish that I’ve had for a couple years to have a better/nicer home. I followed all of the directions to a T and within 2 hours, I noticed my fish kept being pulled towards the top of the bowl and then was almost completely idle near the surface. I got him out quickly and put him back in his old environment where he’d been just fine 2 hours prior, but no improvement. 12 hours later he has sunk to the bottom and can’t even swim, just down there gasping. This is devastating. Some people who also lost their fish from this product are saying it’s the filter, but I also think there are serious issues with the conditioner and bioagent they supply and insist on you using; potentially leading to sudden Swim Bladder Infection. I was nervous to not use what had been working in the past, but I thought, “the rocks and products in the filter might be different and need this specific water treatment.” I feel guilty for my fish.

This tank is easy to clean, just the right size and very cool looking compared to the boring aquariums we are used to.

Cool tank. I can see the filter being a pain in the ass to clean as you are going to have to take the ornaments out to take the filter out. Plus the initial installation of the filter took a lot of grunt work and spilling of the charcoal. Maybe it would have been easier if I read the instructions. Could use more rocks though, only a small bag comes with it. Other than that it is fantastic. Light is super bright.

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 :))

Bellissimo da vedere

Absolutely beautiful 😍 Great price and exactly what I wanted. Very easy to set up & I’m really happy I purchased this!

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

Lightweight and perfect for a few fish. Pump works well and is silent. Great buy
