Do suckerfish lay there eggs in groups?

It depends on what you mean by "suckerfish." There are actually two main groups of fish called "suckerfish":

* Remoras: These are the fish you might be thinking of, the ones that attach themselves to sharks and other larger marine animals. Remoras do lay their eggs in groups. They lay clusters of eggs on surfaces like rocks, coral, and even the bodies of other marine creatures.

* Suckermouth Catfish: These are freshwater fish that are popular in aquariums. Suckermouth catfish also lay eggs in groups, usually in caves or under rocks.

So, the answer is yes, both types of suckerfish lay their eggs in groups. However, the specific details of their egg-laying habits can vary depending on the species.
