Can my 20g support any more fish?

It's a fully cycled 20g, here's a link to the specs:

00ej8's Freshwater Tank, "The 20 gallon tankatorium"

I've lost one of the sunset wag platys, but I believe he was sick from the get go.

I want some cories, but I think i'm probably pushing it.

What do you guys think?

By the numbers it is overstocked unless the platties are smaller ones.
6x - Zebra Danios 12 inches
5x - Sunset Wag Platy 10-15 inches
1x - Dwarf Gourami 3 inches
1x - Oto Cat 1 inch

I would recommend getting 3-4 more otos regardless as they produce little waste and prefer to be in groups. I do have a single one in my tnak now but he sits and mopes where he used to interact with the others before my power outage made him a singles fish. Make sure to feed the otos though as the tnka is new and probably doesn't have much algae for them to eat.

I do not think it overstocked though. But adding more moderate waste producing fish is not a good idea right now.

both the danios and the platys are small. even the gourami is less than 3 inches at this point. I'll add a couple of otos in a week or two.

How do I make sure the oto is getting enough food? i add sinking algae wafers about twice a week, but i don't even know if he finds them before they disintegrate.

Many otos will eat only algae. I think twice a week isn't enough. Real algae of course is much better for them. Try sitting a rock in a jar in direct sunlight which should grow some algae on it.

I would say not to add anymore fish although like fish4all said another few otos would be a good idea but generally I think you are well enough stocked as you are.

I agree with Fish_4_all and Falina. I wouldn't add anymore. Even though the fish are small now you have to stock your tank keeping their adult size in mind. Fish can grow quickly!

150 Gallon - Mostly American Cichlids
135 Gallon - Angelfish Community
75 Gallon - Odd couple (Polleni/Angelfish)
55 Gallon - African tank
20 Gallon Long - QT
10 Gallon - Empty
