Do you mean the aro,if so no the decor doesnt bother him at all,he likes to sit in the plants sometimes and chill,and this is halfway up the tank lol,its almost like he likes to surprise us where hes going to come out ,since i put the tinnys and the dat in hes never been happier.
Sorry lookyloo didnt mean to ignore you,as for your question,he does have a go at the tinnys sometimes but it doesnt seem to bother them,he doesnt go near any of the polys at all and the dat puts him in in his place,like i said its quite a chilled out tank the only thing that could be a problem is the dat getting a bit too bossy with the aro.
