First FYI there areno true freshwater eels, only eels that have swam up rivers and collected. FW eels are actually adapted fish.

Peacock eels seems to stay very small. If it's not a peacock I'm sure it will get way to large for the tank

technically the peacock eel, fire eel, tiretrack eel are not even eels and will get up to a foot or so depending on type. most likely it will eat smaller fish and invertibrates in the tank.
also, the snowflake eel can go from saltwater to brackish and for a short time when younger live in freshwater. its possible to live in freshwater through its life, but it would be a short one.

10g: QT BGK
12g SW: 2 percs, 5 snails
30g: 3 guppys, 4 panda corys, 1 gourami. 3 black skirt tetras, 3 otos, GBR pair
55g: 4 discus, 4 spotted corys, 4 otos, 2F GBRs, 10 neon tetras
55g: 5 platys, bristlenose pair, 2 guppies, 11 black kuhlii loaches, 2 otos, 3 little angelfish
75g: 1 clown pleco, 4 otos, 1 black kuhlii laoch
plus 3 cats, a dog, and a hammy

Kuhli loach?

That aside, there are a couple of species of spiny eels that stay under a foot. A quick look a the species list for Mastacembelidae on fishbase shows a number of them in the 8-12" range. Macrognathus circumcintus is supposedly common in the aquarium trade, and should max out around 8".

u can also buy whats calld freshwater moray eels. i bought one for really cheap. they are actually brackish and in time full marine. those guys will survive for a little while in fw but will soon develop a slime coat and stop eating. they get a fair size too. this is a pic of mine.

depends if they are talking about and eel or an eel -like fish for example a kuli loach looks like an eel,acts like an eel but is NOT an eel while the fw moray is a true eel there are hundreds of eel like fish in the aqarium trade and only very-few true eels

It's probably one of the two species of Violet Gobies, then. Small is relative, though. They can get up to 20", though they usually stay closer to 12". They prefer a tank that's at least 30 gallons and 36" long, and like their water slightly brackish.

Here's a good page on them: Violet Goby FAQ
and another
