Help me ID my Oto cats?

[Aysvin]

I can't seem to figure out the species, many look similar to each other.

They are either

• 
  [*]Otocinclus macrospilus
  [*]Otocinclus vestitus
  [*]Otocinclus vittatus
  [*]

I want to say they're macrospilus, but I'm not sure. So here's my oto, named Auto. His/her friend, Bots, is hanging around on a plant to the right, out of frame. Bots looks exactly like Auto except he/she doesn't have a stripe in his/her tail fin.



I think I'll take vittatus out of the running, Auto and Bots' spots aren't as prominent and they don't have the gap between their back coloring and their stripe.

Wait...now I'm leaning towards vestitus...

Looks similar to my Siamese Algae Eaters that quite often get confused with others. SAEs aren't even catfish, they're part of the shark family from what I've read.

They're definitely ottos. I just can't figure out which ones. The store I go them from has SAE too but had these guys in separate tanks. Besides, they look like the pictures in the links I posted.

Pretty much answered your own question then.
