Knight Gobies

[Docsoldlady]

I was at my LFS Saturday and I saw 2 knight gobies. They are in perfect fin, look healthy, etc. The guy says he has had them about 2 weeks now and is keeping them in freshwater. I want to buy both of them one seems a little larger than the other. I said I would wait. I want to learn some more about them. My understanding was most gobies are brackish, or salt I know some can live in fresh. I googled them and seem to get a mix of results some saying brackish some saying fresh. Does anyone have these little guys in their home community? Could you tell me a little bit about them? Their environment? Can they live with other fish? What do they eat? Etc....I have a 30 gallon that will be free pretty soon because I am moving the poly into the 75 gallon one the re-caulk is done curing. Is a 30 gallon big enough for 2?

Any help or information is greatly appreciated.

Yeah.30 gal is plenty for 2.I would actually suggest you get more and do a breeding project.They can be a bit agressive and are very east to feed and frow to 7.5 cm (3 inch?) I have a pair of peacock gobies and I love them =]]They are brilliant for a community tank.Yeah some knights need brack but if they're being kept in freshwater in you LFS then they should be OK!

Well I got them yesterday...let's hope they work out. I added a little salt to the water but nothing crazy. Pix as soon as I can figure out how to make them show up better, big gray blurs.
