Question on Otos
So, I bought two otos last week to put in my ten gallon whose only other inhabitant is my male VT. The first 3-4 days, they were super active. The last few days, they mostly hide out. They change spots every now and then, but I never see them chasing each other anymore or dancing up and down the glass like they used to. I never see them eat, though they must be getting something because their bellies are round- not as round as they should be, though. My tank has a ton of diatoms, about the same amount as it did when I first put the otos in- my water has silicates. I've also been trying to supplement with veggies, to get them used to veggies in case I run out of diatoms/biofilm. BTW, the veggies haven't been very successful- no one touches the zucchini, and I've tried 3 slices so far; peas are a no go because my greedy goblin betta hoards them to himself like he's Smaug; the carrot was semi-successful in that one of my otos ate some.
The tank is heavily planted and has lots of hiding spots for the otos, but my betta likes to chase them. He doesn't try to nip them, and as soon as they stop swimming he loses interest, but when they're moving, so is he.
I'm worried that because they are only two, they are too intimidated by my betta and that is why they aren't active. Perhaps they are too intimidated to go out to eat as often as they should. I know that otos need groups to feel secure, but I originally only got two because I read that a 10 gallon will only have enough algae to feed two, and I figured that it would be better for them to have the majority of their diet come what they eat in the wild.
Finally getting to my question....does it sound like I should get more otos so my little guys have some security from my big guy? Would the otos be better off with a heavily supplemented diet and more security? Do you think my otos would start eating more if there were more of them?
