Gumball Fish Tank

Gumball Machine Fish Tank

if you have a big tank already, that way new smaller fish have a chance at getting bigger before bigger fish in a tank try and fight and or eat it like some do. again im not being rude but all these comments arnt even recognizing some of these... Any tank or container should be cycled before you add fish and after it is cycled, you have to keep checking the water for Ammonia, Nitrites and Nitrates to make sure they are all within the correct parameters. You might also do well with a trio of Least Killifish, but these are easily stressed little fish that would require dense vegetation(which may be hard to grow in this tank). If you want to keep females, buy one to three females per male in the tank. The smaller the tank, the harder it is to keep within these parameters, ESPECIALLY with goldies since they are so messy. Bettas are more comfortable in 5 or 10 gallon tanks. they consulted with the seller of the fish and based on THIS fish it should be fine for up to 6 months before needing to be moved. As I've said before, this might be okay for shrimp or snails, but most fish won't be comfortable in this aquarium unless you went into some of the more obscure and smaller species, but they tend to be fragile and harder to take care of. PS- a good... From my experience with keeping guppies and other livebearers, I would say no. A ten gallon aquarium would be better for guppies, seeing how active these fish are. Goldfish are inexpensive and cute, but they're not toys- they need as much research, care, and money as just about any other large aquarium fish. Plus, it would be a shame to not have such beautiful fish in clean, clear water under light where you can see just how beautiful they are. i think anyone with common sense would know fish get big and need to be moved so all these comment's about it are unnecessary. or at least it didn't seem like it. and i know how messy they are lol i've had lots of fish. These are tropical fish that need heated and filtered water. This is too small to let most species of fish thrive. Please people, do your research BEFORE you ever get your first fish. that would be epic for fish. bigger gumball machine and add some heater and filters. you know those GIANT gumball machines outside of stores. ALSO gumball machines come in lots of sizes. Most people have never seen where wild Bettas live, and don't understand that they DO live in fresh, open water. The high death rate of goldfish in bowls is caused by lack of oxygen, the small amount of space, and dirty water. again i wasn't being rude or anything was just stating that it was said in the instructable it wasn't permanent and no one even took that into account. Goldfish are *very* messy and produce too much waste to make living in a bowl feasible. Goldfish grow to be six inches or longer and require very large aquariums. I have to chime in on the "THIS IS NOT A GOOD IDEA" camp because goldfish need sooo much more room than this, but that is only a fraction of the issue.
