    • Worth the Money - Long As You Set It Up Right
Style: Series 7 Color: Black with LED Lighting Size: 8 Gallon
Review Image by Harp Gal
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! -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!! ... show more

    • Pretty
Style: Series 7 Color: Black with LED Lighting Size: 4 Gallon
I've had this tank for about two months, and I love it! I don't have to clean it as much. Just change the water. I also folded the air tube to decrease the bubble flow. My old tank had to be scrubbed out constantly. For one betta fish. In the bio orb I put my betta in, and gave him a mystery snail cohort and I've had zero issues. It's pretty and asthetically pleasing. ... show more

    • Attractive but a bit noisy
Style: Series 7 Color: Black with LED Lighting Size: 8 Gallon

Nice little aquarium with ideal filtering system, but the air pump was too loud for my taste. It made a loud humming noise, so I replaced the original BiOrb air pump with the Tetra Whisper, an inexpensive fix. All is good now.

    • Absolutely beautiful, and I was so excited to get this tank, but then...
Style: 4 Gallon Color: SILVER Size: 4 Gallon
I'm still not sure what to say about this tank. I am still fighting with it to get it cycled properly. I have the 4 gallon, and the bigger tanks might be easier as far as care goes. However, it is clear to me that you would need to follow their directions very closely as far as when to add new fish and only adding 1 at a time. That makes it very hard if you have a schooling fish like corydora catfish or neons. If you put in just one of a schooling fish, the poor thing spends all its time looking for its friends. PROS: Beautiful aquarium. The fish in the back look magnified so you can see them more clearly. When the water quality is good, the fish seem happy. The lighting really shows off the fish. Pump can be a little loud, but it's not too bad. All the filtration is hidden, giving the tank a sleek, clean look. CONS: All the filtration is hidden at the bottom of the tank, and thus is harder to get to for maintenance. You have to use their ceramic media for gravel. It is big and clunky. I had hoped to keep dwarf seahorses in this tank, but if there are babies, they prefer a sandy bottom rather than getting trapped between the crevices of big clunky pieces of ceramic gravel. BiOrb says you have to use their ceramic gravel for filtration to work properly. Due to the aquarium shape, there are parts of the bottom you cannot see. This means if a fish is feeling poorly, you might not be able to find it to do anything to help. Also, if you are doing any cleaning with a tank vacuum, there is not much room and you can't tell what you are doing. It seems like more work to keep the water chemically balanced in this tank than in other tanks I've had of a similar size. The filter cartridges are expensive, and you pretty much have to remove much of the decoration to change it. There are reviews that talk about using fish aquarium charcoal in the original filter, and I may try that. I would also keep the existing sponge and rinse it in the aquarium water during a water change rather than put in a new sponge for the filter. Even though they give you a package of bio organisms to add to get the biological filter working, the water quality went way down after I changed the filter the first time and I thought I had made a big mistake. Next time I will do it the way one of the reviews said to do it with the aquarium charcoal and the same sponge. Overall: For keeping seahorses, I decided this just would not work for me. I put a beta in it and then 2 corydora catfish. It seemed fine with the beta and a plant, but when I added the cory catfish later, it took me several weeks of daily 10% water changes and conditioner to get the tank back in balance again. The directions say add 1 fish at a time, and I think they mean it. Also, I am pretty certain my tank was not fully cycled when the beta moved into it. The beta seemed happy, but the cory catfish were stressed when they arrived. Then started the daily water testing, conditioning and water changes to try to keep the fish alive and happy. When the cory catfish are stressed, they swim laps around the aquarium. It takes them about 5 seconds, and 3 seconds when they are really stressed. That is my queue to do a partial water change again. This aquarium has taught me a lot more than I knew previously about cycling the tank and testing the water. I am still trying to get this tank cycled. The water nitrite levels seem to go up so easily. I ordered the tank on January 5th, and here on March 5th, I am still wondering if this is going to work in the long run. When the water chemistry is right, the fish are happy in this tank. I have little castle and tunnels in the back for them to hide in, and plants (one real and some silk). The cory catfish seem happy at the bottom, and the beta alternately rests on one of his favorite leaves or floats up like a king to see if it's dinner time. There are also 2 snails to help with cleanup. This is max capacity for my Baby BiOrb. I guess what it comes down to is if you are prepared to work at it, this tank is a beautiful home for a beta. Just be sure you have the tank fully cycled before adding fish "1 at a time every 28 days" as the instructions say. I added the 2 cory catfish at once, and that was too much at once. I am also in the process of cycling a larger tank to make ready for the beta just in case this Baby BiOrb does not work out for me. If you decide to buy this tank, be sure buy a water test kit too. Then google "Cycling your Aquarium". Don't just let it run for a week like the employees at the fish store say. There is much more to it than that. Good fish for this tank would be a single beta or a couple of mollies. The mollies are a hardier fish than some and perhaps will not be too sensitive to the touchy water chemistry balance. I will update this review later when I get the tank better established and see what the upkeep will require and if the fish are still happy. ... show more
