new marble goby, water cow

[samnteeg]

last week we got this wonderful fish i've seen them called by both names and i have no way of posting a pic. the store called him a marble. i'm reaching out to anyone who has had 1 of these fish for a period of time. wondering what foods worked best for them and how fast they grew?
mines only 4 or 5 inches long. have him in a brackish tank with 2 velvet gobies/ dragon fish both a couple yrs old and about 8 inches long, an archer fish, a spotted puffer, 4 mollies ( had several more but marble ate them).1\2 the tank is sand 1\2 rock. marble seems to like the rock where the dragons LOVE the sand.
any suggestions would be great.

thank you for the reply, but the question was what foods ppl had best luck with and how fast they grew. not how much they ate and how big they got.

Marble goby and water cow are two different species. Feed them anything meaty. I've kept them in FW and BW before.

Expect to have missing mollies and GSP's before long.

They eat anything moving that they can fit in their mouth including each other. That answer your question? They get 2' long.

Pretty sure marble gobys and water cows are two VERY closely related species, both get around 2-2 1/2 feet and around 5 lbs, if housed with other fish there definitely has to be adequate room if they're sub or adults, sometimes up to 300 gallons depending on their specific temperaments. You can feed them live or frozen foods, but it's possible they'd reject pellets, and never eat flakes. These fish are not full when they're ballooned, they're full when they look thick, if they're ballooned in the stomach you're definitely overfeeding. They do best in brackish water, it's where they're actually found, but do completely fine in full fresh as well. Be wary as they can become VERY VERY aggressive as they grow, and even as babies they'd appreciate good sized feedings every other day. The favorites are usually something like tilapia or smelt, and some shrimp or krill in the mix, but you should definitely experiment on what yours like.

You didn’t ask........ but with regards to if you have a water cow or a marbled sleeper goby. If yours looks like this it is a Marbled

A friend caught this Eleotris for me back in July, at about 8" , it's in a 180 gal tank.

The other day it happened to sit in front of the ruler. I feed it maybe every other day, fish meat, or the local shrimp.

It is housed with about a dozen 3" to 5" Andinoacara cichlids, I expect to start losing the smallest cichlids soon, unless i can fish another suitable sized tank.

Above a recent shot when it perched near a ruler, has gained some extra girth too.


It changes color and color patterns frequently with mood, or hunting style (position), or sunlight.
