I currently have a Hujeta ("rocket") Gar already. Other than that, I just have 2 giant danios and an albino rainbow shark. So, I'm looking at re-stocking a bit. I've previously kept a Maculata ("South American Spotted") Gar and a black ghost knifefish in the tank, although I knew both would outgrow it eventually. However, both died prematurely in unrelated incidents. This time, I would prefer to get something I can plan on keeping in the 45 long term. One option I've looked into is the Brown Ghost Knifefish, because it only gets to be about 13" or so. However, I have seen a few things about those not being as healthy, so I'm not sure if that's the right option. Any suggestions would be appreciated, thanks.
 
So, right now I think I'm going to bet a brown ghost knifefish with a senegalus bichir. The only other thing I might need would be something to fill out the middle level of the tank. Would a couple more rocket gar to keep my solitary one company be ok?
 
I had the exact set-up you mentioned: Sen. bichir and brown knife. Fun combo, though a small false gar would have been fun to have floating on the top. My bichir and brown knife are actually still together, just in a larger tank now.

Kind of an off-subject question, but my gar has always hung out near the bottom of my aquarium during the daylight hours, it only stays at the surface during the night or early morning. Is that anything to be concerned about? (you an probably tell I'm kindof a noob)
