So decided to splurge on an expensive fish for my 75 gallon tank a month ago and buy a gold nugget pleco. Figured he would be like my bristlenose. Hiding a lot but still occasional present. Well a month later and never leaves his plastic cave. Can't even see him cause he curls up in a ball on the top part. Only reason I know he is alive is cause I see pleco size poop in cave. Don't even see him eat or leave cave when lights are out. No fish that should scare him. He and brown knife fish are biggest in tanks. Would it be cruel to remove that cave. I mean I would like to see my 60 dollar fish occasionally. Is there anything I can do to make him a lil less reclusive?
