I was wondering if I should decorate the tank. I've had problems with the fish fighting before but since I got the tank I've had no problems. I think its because they dont fight over territory since there is nothing to hide in. Should I leave it or put in hiding spots? I was thinking of putting just one piece of driftwood smack dab in the middle and nothing else. Finding hiding spots for fish over a foot long has been very discouraging. I have a gar, oscar,pike,goby,texas,jag, and jurapari.
