Hey guys my Grandma really wants some pearl anglefish she saw at the fish store we went to and a black ghost knife fish that she had when she was a kid. I'm looking for either a 30 or 40 gallon tank for her at the moment and I had some questions about the anglefish and the black ghost. Is one Black Ghost going to be able to live with five Anglefish in a 30 or 40 gallon tank because she really wants them and we are going to get a pleco too maybe a golden nugget or vampire and would they be bothered by the Black Ghost? Because when she was little the fish store owner said that the Black Ghost she was buying would be fine with her fancy tail guppies but one by one she said the guppies lost there tails from the Black Ghost and I don't want that to happen again.
