I bought my gold nugget pleco with the idea he would grow as fast as the other fish in the tank. This is not so. It is 3 inches and I bought him 6 months ago at about the same size give or take an inch. Now in the tank with it are some larger fish. There is a 4 inch Bichir, 7" jurupari, an 8" black ghost knife, 4" crayfish, 13" caecillian worm/eel. Im worried most about the bichir and the knife. Do you think it is safe or should I pull him out and put him in the community tank. It is in a 75 gallon now and the comm. tank is a 65 gallon sump. Thanks
