Certainly, otos need a mature tank to survive, with plenty of surface algae....otos constantly forage on algae, and will starve if there is not enough algae/biofilm in the tank.For both : Get healthy ones (not skinny) + put them in a matured tank.

They will graze on algae wafers, but algae is the main staple of their dietIs there a commercial food they would accept ?
A tank should have been running at least 6 months after cycling before getting otos. They need a mature tank as well as algae.
It is possible to grow algae for otos. This just involves keeping a few rocks in a glass container in tank water on the sunniest widow sill you have. When algae has grown on the rocks, one of them is placed in the tank, then when that's been cleaned it is returned to the container and another algae covered rock put in the tank.
