I wouldn’t recommend a 17-liter tank for a fancy goldfish. If your fantail is still young, you might get a couple months out of it, but eventually you’ll want to purchase at least a 76-liter aquarium (or 20 gallon tank). Your goldfish may even do fine in a 38 or 58-liter tank (10 or 15 gallons) if you simply don’t have the space for a larger aquarium right now, as long as you stay on top of water changes and water testing. Make sure you also have a good filtration system (I personally use power filters in my tanks, but canister filters are also very good). If your filter needs the extra help, you can even attach a sponge filter to the glass – these filters are really good at biological filtration. Fist let me tell you all about the tank: 5 gallons over 6 months old added 7 neons 3 weeks ago along with some anubias and anacharis. FISH:

“The bigger the aquarium, the easier maintaining it will be.” This is probably the single most important rule in the hobby, and for someone setting up their first aquarium, it is an absolutely essential fact of life. The size of the aquarium has a direct impact on several key physical and chemical processes, including pH stability, thermal stability, and the dilution of metabolic wastes such as ammonia. The smaller the tank, the less stable and the more toxic the environment is likely to be.

The size of the aquarium is also important in terms of how fish behave. Schooling fish need to be kept in groups of at least five or six specimens, and that it turn requires a certain amount of aquarium volume and swimming space. When kept in insufficient numbers, barbs, danios and tetras become frustrated and often turn aggressive or nippy. Territorial fish need to be able to claim a certain patch of ground, and if there isn’t enough space in the tank, fighting or bullying can occur. Livebearers pose a particular set of problems because of the way males fight with each other while also tending to bully the females. It is important that there is enough space for the male and female livebearers to spread out, and if necessary find hiding places where they can rest or give birth safely.
For all practical purposes, the minimum “safe” aquarium size is 20 US gallons (75 litres). Such a tank will be big enough to accommodate a reasonable selection of small aquarium fish without being particularly large or expensive. More ambitious aquarists interested in big or territorial species such as cichlids should consider larger systems though, with tanks up to 55 US gallons (210 litres) in size providing a good balance between size and expense.If your aquarium is bigger than 15 gallons (57L), you can keep your betta with some types of tank mates. Stick to fish and invertebrates that are calm, won’t nip your betta’s fins and are big enough to avoid being seen as a snack by a hungry betta. Don’t get tank mates that have different requirements than your betta when it comes to water values and temperature. Do some research before running out to the pet store.I just moved and my old tank was a 75 gal with 24 small fish in it (like the size of neon tetras and cherry barbs) it was a planted tank as well. since we moved I set up two 5 gal tanks (well 1 is a 5.5 but you get it lol) one of the tanks is your average 5.5 gal and the other is the Fluval Spec tank so its longer than it is wider, I have 9-10 fish in each tank because all my Local fish stores wouldn’t take my fish (missing a good offer for free lol) so I have them like I said 9-10 in each, with my other tank/tanks I was really good on keeping it clean and the plants and some of the fish helped me keep it clean to, so will these two 5 gallon tanks be ok with the very small 9-10 fish in them? and also im good about keeping required PH levels and average cleanliness of the tanks anyway but will the fish be ok, they seem to get along and be swimming calmly just acting normal. ???recently replaced a 10 gallon that had housed 2 goldfish for 15 years. got another 10 gallon, a marineland, but am having issues getting the goldfish to live so I decided to go tropical. read what type are good fish for a 10. with my older tank the hood broke so I decided to go with a penguin filter that would clean a 75 gallon. with the live plants, near a window and the waste producing goldfish this was fine and kept it very clean. I don't think the small penguin will keep the tank clean. I don't mind changing but how do you get a hood with lights that will accommodate this change. I do like the led nights that this hood has. read through your threads and have gotten excellent info.
