Hello -

Am currently re-stocking my 29 gal. planted BW tank. The first resident to go in there (once the tank has cycled fishless) will be my knight goby, who's currently in QT. I also want to add a F8 puffer. I run the tank at 1.005 SG (I know the knight goby is listed above as being a "higher salinity" fish, but I've kept him happy and healthy for about 4 yrs. at 1.005).

What other fish might I add to this mix? I'm interested perhaps in a dragon goby - how would this interact with my knight? (The knight is extraordinarily shy; there are lots of caves and driftwoods to hide in). Also am considering mollies, orange chromides, and/or bumblebee gobies (same question as above).

What would people recommend?

Thanks!!

Strike this - just saw it gets waaaay to big for a 29!

Probably not best to ask this question on a pinned topic. It's generally better to ask specific questions in the forum proper. Pinned topics are most useful when they stay focused on general info rather than helping different people out.

But briefly, A 29 gallon would be fine with orange chromides (fun to breed, though not easy). Knight gobies don't need an SG above 1.005. Not sure why they are listed as such. 1.010 is tolerated rather than preferred. Anyway, they are fine with orange chromides, but being predators, they will eat any baby chromides. Figure-8s are fun but a bit unpredictable. Not recommended for community tanks, but they sometimes work fine. Depends on swimming space, number of caves and plants for hiding places, and the personality of the tankmates. A 29-gallon tank is not huge, and although brackish water contains only very slightly less oxygen than freshwater, brackish water fish generally lack adaptations (such as air-breathing) for dealing with overcrowded tanks. So stock slowly and plan for growth.

Good additional fish (assuming you have space) for chromides and knights include sailfin mollies, waspfish, clay gobies, crazy fish, flatfish, and glassfish. Bumblebees and wrestling halfbeaks would be fine with the chromides but likely to be eaten by the knights.

Neale (all),

My apologize re: this...I was wondering about that, but saw that the other "pinned" topic had about 20 or so replies (and I didn't start that thread!) Also, please forgive me - I am from the U.S. and wasn't altogether certain what "pinned" means...

Now I know better - sorry again. Please feel free to move/delete my portion if necessary!

Thanks for all your help - I sincerely appreciate it.
And, for what it's worth, I have your new book on pre-order from www.barnesandnoble.com - can't wait to get it, as your info. has been invaluable thus far

Hey, thanks for the kind words! The book is just my work. In fact, some of the other authors are much better aquarists than me. I'm proud to have worked with them.

The main difference between pinned topics and the others is that people don't really check the pinned topics for follow-up questions. So if you post your question on a pinned topic, it might not get looked at. You might want to copy-and-paste your question into a new post on the brackish forum proper, so other people can take a look. There's some really talented aquarists here. Have a browse of the topics with photos. Some of the tanks are very inspirational.

Cheers,

Neale

Just a couple thoughts if I may be permitted, and please feel free to delete this post. (-:


I noticed you have a symbol for when a species has a profile written, but I don't think that has been updated recently and thought you might like to know. (-: Iknow at least the mollies and kirbensis and bumble bee gobies have profiles. Maybe I missunderstood the symbols though, so if so you have my apologies. (-: I just thought I'd mention that. Have a great day!
