Yeah until it gets big enough to eat them. what type of shovelnose? The jag might be a little to rough for a young shovelnose. a dempsey will get about 10 in. for male 16 inch male jag. so the shovelnose can be about 18 inches for the dempsey 24 for the jag at adult sizes. meaning at 7-8 inches bigger then the cichlid, it can look at them as food. some like m. tigrinus can be 5 inches biiger o consider them food. how big is the tank?
