You go to the pet store and you look at decorations you don't need and just want.... or you buy it anyway even though you don't need it and have to figure out where to put it, and sometimes something else must come out of the tank....
We bought two new decorations (1 for our 20g 1 for our 5g female betta's tank) yesterday, 1 needed, 1 we really like, and yes, something had to come out lol. Will probably put that in our 10g tank.
All we have to decide is what to do with the time that is given to us. –Gandalf- 20g high community tank, 5g w red male betta, 10g w crowntail blue male betta & 4 Amano shrimp.
