Do fish have friends?
 

I know there are people that say clown loaches are full of personality. My question is, do they establish "bonds" with other clowns?

In time, I will need to find new homes for my two clowns. Not any time soon though. They're still small.
Has any one ever separated fish and noticed a difference in behavior?

I ask so that I'll know whether or not to relocate them together.
...or maybe it doesn't matter as long as they're each placed with other clowns?

Many fish appear to form bonds with each other, and some seem completely unfazed at the removal or death of another. I personally have not kept many loaches though. What is their behaviour tending towards? Spending large amounts of time together and showing little aggression is usually a sign of a bond.
