Is An Otto A Pleco?

[blackfinshark_3]

In my 35g i have 3 otto's and the tank is fully matured with

0 nitrate
0 nitrites
0 ammonia
and 7.0 PH

what are the pro's of getting larger numbers of otto's? if i got another 5 otto's would the 8 of them school together or is this bogus and they'll just spread out like they presently are?


thanks for future help


P.S:sorry if this is in the wrong forum!

An ottos is not a plec, but ottos and plecs are both Loricarids.

There was a discussion about the sociability of otos HERE

I'm not sure we really achieved a consensus on the question, but IMO it you like them get a few more. Great little fish!
