My Otos are really skinny too and I can't seem to make them eat either.

I think I'll stop buying them altogether. They are typically wild caught with chemicals dumped in natural water sources. I'd rather not encourage that. Unless someone has found a captive bred strain?

Mine love blanched Organic Baby Bok Choy.

Steam for 3 minutes take out put in cold water and then take skin off and put it on a clip or rock with rubberband.

Mine loves cucumber, especially the seeds. I don't blanch it, just peel it so it sinks faster. Shrimp go crazy for it too.

My otos eat cucumber and zucchini. I have some in my husband's tank and they are always plump so I only give veggie once a week. The batch in my 55g are idiots and don't eat the diatoms on the glass or goodies on the driftwood so I have to give them a veggie every 3 days (about how long it takes for them to pick clean a chuck)

Due to photobuckets new bs cost for use of images on forums I have deleted all photobucket accounts. I apologize if you enjoyed or found my photos helpful.

I have 3 otos. 2 older ones that became extremely shy, and one I have acquired recently (and which has come with extra gift of ick, LOL).

I am giving them cucumber and Hikari Mini Algae wafers.
The old otos became very shy, just hiding on the back wall of the tank behind the heater or plants of driftwood, I do not ever see them eat.
The new oto is always next to feeding dish munching on the algae wafers or sometimes eating the cucumber.

There is a ton of algae everywhere, especially on Anubias leaves, but some of it seems very hard - I have hard time scratching it off with my nails. The snails seem to eat it, but I don't think otos do. Every time I change the cucumber bit, I throw away several snails. But they keep coming ;-)

I fear that my shy otos are going to starve. I don't know how to change their behavior and make them eat and come to the front of the tank.

You can be certain they are at least eating at night.

I thought mine were going to starve, had algae to be eaten, then began noticing the algae was always missing when the lights came on in the morning.

I never got mine to eat anything I tried to feed it, so I gave up and he's still happy and fat off what is in the tank...many many months later. These things really are amazing at cleaning your tank.

I tried most algae eaters, snails, amanos, and these Otto's are on another level.

Lets hope so. They are nice little creatures it would be sad if they starved.

But I would also like them to be more visible in the tank instead of always hidden. I just bought some Omega One Super Veggie Green Seaweed, maybe this will lure them out.

10 gallon w 1 Otto.

20 gallon w 1...had 2 but one didn't survive the move

Idk what repashy is but I will Google that.

Thx.
I got some of the Repashy Soilent Green and every animal in my tank goes nuts for it. I have nerite snails, a school of chili rasboras, cherry shrimp, mystery snails and three otos. It's a little insane.

Make sure you prep it correctly, or it won't turn into a firm gel. I followed directions that told me to add the powder to water that had been brought to a boil, which I did, but it didn't really solidify. The second time, I brought the water to a boil in a tiny pot I had, and then added the powder, let it boil for a few seconds more while I stirred, and it worked like a charm. I poke a chunk of it onto the end of a steel skewer just to get it down to the feeding dish, tap it lightly, and it falls off. Maybe they all take that as a dinner bell ringing or something because within just a few seconds, they all start converging. It doesn't gunk up the tank AND stays firm until it's gone, which doesn't take long. ☺️
