I have two clown loaches, and I just noticed some strange behavior today.
They do this thing that looks like they are kissing, then they swim a little bit.
And they keep doing this same thing over and over again.
Also, they have very bright, distinct colors. And they appear to be about 4 inches in length.
And one appears to be a little plumper than normal.
I'm thinking it might be a spawning thing, but it's a rare occasion in home tanks.

Has anybody had this happen?
What happened?
Thanks!
