Thx. For sure is goniobrqnchus lineolatus... I guess it safe top keep it right? Does no harm to my reef tank if it only eats sponges. I dont think i have any sponges but in the last 2 months it grew so it has to be eating something

If the species of sponge it was eating was toxic your tank or the wild. It does retain those toxins for an extended period of time; one study i read said years after last consumption. If keeping, a heavy amount of gac might be suggested, to be safe in case it passes.

It is impossible for the nudibranch to survive 2 months without primary food source.
