We've only recently moved our beautiful betta boy into a ten gallon tank. The tank has sand, live plants, some driftwood and currently the only other occupant is a ghost shrimp named Scampi.
We noticed after a few days that our Betta (Zaphod) was flaring at the filter through the glass. We tried to cover his view of the filter, but he continued to flare without stopping. We tried moving the filter, changing its settings, putting up a background, changing the lighting in case it was his reflection he was seeing, but none of it helped. Finally, to prevent him from exhausting himself, we just put up a tank divider to keep him away from the filter.
The next day we found he had begun to build a bubble nest along the divider.
At any rate, we now have the right half of the tank looking rather dull compared to our bright guy on the left. Are there any possible tank mates that would do well in half of a ten gallon tank with a betta next door? The divided space doesn't really seem big enough for schooling fish, and so we're unsure of what might do well there. We would prefer to avoid any neighbors that Zaphod might see as competition.
