Hi everyone, Steven from Belfast n. Ireland. I been keeping fish for 5yrs now mainly cichlids. I've recently talked my girlfriend into settin up another tank which I decided to keep L no.s catfish. I've got a golden nugget,snowball and a royal panaque in a 4 ft tank. I've seen a beautiful acanthicus Adonis which is about 7 inches including tail and would love to add it to tank. All the rest of fish are between 3 and 4 inches long and am wondering if this is a good idea as the Adonis can grow quite large??
