Let me start by stating that this website is sweet
. Okay so I use to have 2 white mollies, 2 red tint tetra's (don't know exact name), and about 30 bristlenose algae eaters. I decided it was time for a change and sold 27 eaters for 4 new domination mollies, gravel, and live plants (something I've been looking to do). I took them out and changed the gravel and such. Now with them all back in there I have had some noticeable change that I want to make sure is okay. The black dalmatian molly is now a bit aggressive, mostly during feeding time or sometime close after to only the 2 white molly. Next the biggest (used to be Alpha)white molly fish is now dissociated. He used to chase the other white molly around (glad he's not anymore) but seems alienated from the group. The white mollies also recently gave birth to 8 babies and I thought maybe that was the reason too. Not sure if everything is normal and I'm just crazy but it seems as though my fishes are changing rank in the molly world, with 2 males and 4 females (8 babies though to hopefully help the ratio). Any suggestions would be gladly appreciated. Also I have a video of the aggression I'm going to try and post soon.
