Hi guys, I am thinking about getting a Dragon Goby and an Ornate Bichir to do a Water / Asian Dragon type setup.
Are they compatible?
And does Dragon Goby need brackish water?
Online info states max size of Dragon Goby to be just 1ft or so but I have seen youtube videos of specimen much bigger than that. What is their actual max size?
Dragon gobies do need low to mid level brackish water. Somewhere between 1.005-1.015, but probably closer to 1.015 as they mature. I'm not sure if the bichir could handle that, but I have very little knowledge on them.
The dragon gobies also get much larger than 12". They easily grow to 24" or more. They also grow much faster than you'd think, considering they are filter feeders. Back when I first started out, and didn't really know any better, I kept two dragon gobies in a 10 gallon bare bottom tank. I kept up with good water changes and they still grew to about a foot within nine months to a year.
You might just try two dragon gobies instead of the goby and bichir. You could also mix some archers or scats, or son's other brackish water fish with them. Scats are always active and make for a very active tank. They might pick on the gobies though, so it might not work that well long term.
