bumble bee goby,are they aggressive

[Bling]

Sorry to sound so stupid, but what do you mean by "whole lines" or "broken lines"? I have mine in pretty strong (I think) salty --- between .008-.005 --- and they're pretty happy, I THINK, but I sure would like to know what type they are. The two pictures look sort of the same to me. What should I be looking at?

ok just to clarify,

the FW BBG is ok to put into a community tank ?? cause it's not overly aggressive it just wants it's own space ?

then 4 of them in my 6'x2'x2' is a bad idea ?

I have two brackish BBGs in a 60L tank with a puffer fish. I have seen them chase each other a few times but more often than not I see them sat side by side, or both standing on the same ornament jumping up to catch some daphina. The puffer and BBGs completely ignore each other.

Actualy there are two different species of bumble bee goby. One is entirely brackish and the other is entirley freshawter.

Brachygobius Doriae are brackish.

Brachygobius Aggregatus are Freshwater.

Both species grow to the same siz and require the same care in almost everything, accept that one is brackish and the other is freshwater.

I'd only heard of the brackish species before. PetCo has some Bumblebees but I'm not sure which species they are. I'll have to go look and see. I might break my promise to myself and buy a trio if they're the freshwater species.

As it turns out it was neither species but the one beginning with an X, and doing some research, it looks like the two Bumblebee species you listed are backwards, almost every site indicated doriae were more easily adaptable to Freshwater.
