I have had an 8" Male Red Devil for two weeks now and he is the most personable fish I have ever had. He always greets me when I walk by and he is very cute. However, sometimes I don't know what his problem is. For no reason sometimes he goes under a big tree root I have and just lays there on his side like he is dying. WRONG! He is just fine and comes out later at night. Other days you can't get him to leave the surface of the tank because he is begging for food. He just isn't aggressive. Some days he will take a nightcrawler out of my hand and other days he wont. Does he need some time to get used to the tank or what? There is no other fish in the tank besides a Pleco. Water is filtered by 2 Penguin 170's and a Fluval 304. Tank is 40 gallons. Water is crystal clear and I do a 40% water change every week. What should I do? He is PERFECT condition on the outside and nice colors. He just isn't aggressive like others say their RD's are. Maybe more aggression will come as he grows bigger? Thanks very much!
