To move a sucker fish from one tank to another, you should first prepare the destination tank with appropriate water parameters matching the original tank. Next, catch the sucker fish using a soft mesh net to avoid injuring its delicate skin and fins. Transfer the fish gently into a clean container filled with water from the original tank, then carefully acclimate it to the new tank's water by slowly adding small amounts of the new water over a period of time to prevent shock. Finally, release the fish into the new tank once acclimated.

You obviously did not do your homework when it comes to the fish you have and their needs. Sucker fish do not eat poop or rubbish. (No fish does that) They are tropical fish and they are algae eaters.
No because they stick to the wall of their tank and clean the walls of the tank.
These fish can be taken care of just like most fish out there. Get a tank with a filter and put them in. Feed the Molly tropical flake food and the 'sucker fish' pleco algae tablets.
No it will get too big
Yes, it is in the sucker fish family.
Likely yes. Most sucker fish need a filter and heater though, and most betta's are housed without these things.
You should not have any fish in a 5 litre bowl

Sucker fish egg colour is bright yellow.
They are harmless and never chase other fish. They help keep the tank clean by eating the algae. It's good to have one in any aquarium.
