I actually started with 5 silvertip tetras, and just added 4 more. They're doing great in their new 45 gallons... well... if spawning means ''doing great''. I just saw a cloud of eggs pop out ! The entire crew was darting all over the place to catch 'em, then checking each and every inch of plants to see if there was some leftovers... It's been up and running since 16 days with lots of plants. Ammonia, nitrites and nitrates levels are undetectable. pH is stable at 7,4.
NOW, these little buggers are funny. The first boss (male) that came with the first batch of 5 was extremely bossy, occupying 3/4 of the tank most of the time. With 4 more, it looks like he can't manage to keep all the tank to himself when there's 8 curious tornados wanting to crash in. Plants and obstacles are very important, as it is clearly the boundaries of each males territory.
I'm willing to get Odessa barbs when the plants get a little bigger. Will start with 6, will add 4 more. I really like them and I presume they can get along fine, according to the fact that they are quick and a little nippy.
Anyone has Odessa barbs with tetras ? Are they really near 3 inches at maturity ? What about your male/female ratio? Are you having troubles with other mid section swimming fish ?
Was also maybe considering some dwarf cichlid (apistogramma or bolivian ram), but not sure about having to deal with a territorial drama in the bottom of the tank if they ever wanna raise a family. What's you opinion on that ? My silvertips are all over the place, from top to bottom...
