My koi recently died after 10 years so I am looking to get tropical fish this time. I was wondering what are some types of peaceful tropical fish that begs for food when I look at the aquarium. I liked the way koi and goldfish follow me around begging for food. I would move to one side of the tank and they would follow me and when I move to the other side, it would follow me.
Right now, I am looking at getting some cory catfish, dwarf gouramis, platies, and/or other type that would beg for food. Would any of these fish live while I cycle my tank? If not, what are some types that can? I don't really want to get danios, but will if it would help.
Lastly, how many of these types of fish would be recommended for a 50gal aquarium and how many of each of these types of fish should I get?
