Maybe I have a lazy or selective RES.
Got her very young, and my son insisted on fish in the tank. Against my better judgement, I added a few black neon tetras and a couple of mollies to the 20 gallon tank. (I know! I know! But I didn't know much back then). Unfortunately, the tank was still cycling. The mollies didn't make it, but the black neons did.
A few months later, we moved to a 55 gallon with a 55 gallon refugium, so 90-100 gallons of water. I added more black neons and some regular neon tetras. Both were fine for a few weeks, until the neon tetras started to drop their numbers overnight. I never saw Tobie chase them, but there'd be fewer each morning. No change in the black neon tetras numbers.
This Summer, years later, I finally got a 150 gallon, keeping the 55 gallon refugium. I added more black neons to replace the ones that had died over the years. I also added zebra danios, black mollies and once again neon tetras. I figured with the tank volume and rocks/decorations, we'd be good.
And I was mostly right. I've never seen Tobie chase any fish. The danios, mollies and black neons populations have remained unchanged. I've even had one danio egg somehow make it to fry stage. However, once again, the neon tetra population has dwindled.
It's actually neat having such a large tank with schools of fish. They don't school tightly, which tells me they aren't nervous. Tobie doesn't chase them, and they aren't even that concerned about her as she swims by.
I'm not sure if she goes after the neons in the night, when they aren't very active, or if perhaps it's just that they are less hardy and she picks off dead or dying ones. In any case, n more neon tetras.
