I added a couple of Otto's to my tank (20 gal
with 4 serpae tetras and 3 harlequin rasboras).
Everything seemed fine for a couple of weeks - there wasn't much algae and they polished it off in no time.
So I got some algae tablets and the guy at the pet store said to only put one in every 2-3 days.
Well - one Otto died, don't know why. I don't think he starved because the most recent algae tablet I
put in there actually bloomed because it just sat there and they didn't eat it.
I have very little to no algae in my tank for them to eat. What should I do?
I want to get another Otto or two so that one doesn't live alone (read that is bad for Ottos) but don't want to kill another one....
Any suggestions on what I may be doing wrong?
