The egg clutches I'm familiar with are clear or opaque, if you like, in a gel and laid in a crescent/horseshoe shape.
Why don't you research the loaches and find one that will snack on snails and 3 or four can be happy in your tank.
If your water is good and you're not over crowded, with other than snails

, you will enjoy them. I love my clowns, and I know emma does. She seems to be well aquainted with the playful fellows and their needs.
I do agree with germanshepard, if your setup is too small, clowns are slow growing but they really can't dance in a small tank and would not be happy long. They grow the first four or so inches pretty fast.
In the mean time cut down the feedings, squash the buggers, pick them out regularly, lure them out regularly. It's a gradual process of consistent application. They won't hurt anything that I'm aware of, may do some good.
Start a snail breeding tank for your coming loaches.

I let them grow in one tank as treats for my clowns
