Small community fish, 6 gallon tank is not much room for fish to move around once you include gravel, plants and other decorations, so you don't want any large fish. Platies, neon, black or glow-lite tetras. Standard rule of thumb is 1 inch of fish per gallon of water.
I'd say a betta, but that's about it except for other small shrimp and snails. If you kept a betta in one, it'd have to be heated (77-83F ideally) and filtered. Also, weekly water changes of 15% would be needed.
OR.........
If you were fairly experienced you could have 5ish endlers livebearers if someone carries them near you. Males are about an inch or so big.
Shrimp and/or snails could also be added....
Only 1. Usually a Betta is all that is kept in a 3 gallon tank
2 or 3
The rule of thumb is usually a gallon per fish, so six gallons would be good. If the fish are on the large side (like a goldfish), then a seven gallon tank would be ideal.
normal rule for fish in a tank is: For every 1 inch of fish there is 1 gallon of water
guppys are tropical fish. they require a heater, and 1 gallon is to small for a heater
id say 15 fish
A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.
length and width for a 55 gallon fish tank
A betta fish would be much more suited to a 1 gallon tank than a 'variety'. You shouldn't keep much more than one fish per gallon anyway.
Remove the sick fish..... the fish that has the ich should be put in a hospital tank then treated for ich, corals do not get ich, only the fish, so a ten gallon tank with a aerator would be ideal for a hospital tank....
This is simply funny if it really means a fish tank.About 1025.5 for a standard 100 gallon fish tank if the beers are 12 fl oz.Remember fish tank gallon sizes are measured by outside dimensions.
just leave 2 mails and 1 female guppy in the tank with no other fish in the tank at all times.-Shocker There should be 3 females to one male. If there are too many males, the females will get stressed out. I would recommend a larger fish tank than a half gallon. Maybe a 10 gallon tank. Remember, you are going to have some babies. Where will you put them?
