Red-Fin Shark vs. Otocinclus

Food a plenty...

Yep, I made sure to bring some algae wafers home with the oto cat. I've already been experimenting a little with blanched fresh vegetables to check his preferences. He seems to like romaine lettuce and a little ambivalent towards cucumber slices. I think I'm gonna try zucchinni tomorrow...
 
I recently had the same problem in my 20 gallon but, the shark killed the oto. I'd also add some more neons. Good luck with your tank though.
 
Meanwhile...

Thanks for the advice everyone!

I definitely wanted to add a couple more tetra. Three seem like a, uh, one-room schoolhouse. I had wondered how much company the oto might want. I didn't want to have too many in my tank and have them suffering for lack of true algae to eat/ pursue.
 
I don't have much to add to what has been said. Other than I appreciate the way you included the age of your tank and the occupants in your first post. nice and clear.
Also, I was wonderring if you are related to silent ray just ray?
 
No known relation. Sometimes I go by Def Ray (also no known relation)...
