I had two ghost shrimp in my ten gallon, and they were missing a couple of weeks ago, and I assumed they were just hiding.
Now they're definitely gone. The weird part is I had only seen Vilkas flare at them once, when they were put in the first time.
Now, I'm putting Vilkas in a 2.5g on my desk, and I might get a dwarf puffer in my ten gallon (my dad is talking about going to our favorite, massive tropical fish store to look at their selection) and I was thinking of putting a ghost shrimp in there to test so I could see if I could get shrimp with the puffer in the future, but if the puffer gets too aggressive, I'd move it in with Vilkas.
The only problem is I'm still not sure if Vilkas killed off the last two or not! Any idea on what might have happened?
