Well my experience with my last two Ancistrus wasn't the best. One got eaten and the other got burnt to death so I'm hoping this time to avoid big of those things. My heater is unplugged since it's summer and the pleco I got today will be the biggest fish in my 30 tall. Just finished up acclimating my brand new 3.5" Albino Blueye Ancistrus to her new home. She's a beautiful fish and has already eaten all the algae off of almost all my decor! No aggression issues as of now and hoping it stays that way. I'll post pictures in a few minutes.
