i have two tomato clowns i bought from a LFS not paired, one however is larger than the other. the big one took to the toadstool the small one to the sebae. for the past few weeks they have been solitary but now they come out and the larger on bolts over to the little one and just looks at it and the little one just instantly goes on its side and fans the big one. does this mean they are pairing up or something?
