Hi I helped someone move today and they didn't know what to with their fish so my girlfriend offered to take them. The only fish I know about are bettas, and the only other aquatic animal i know how to care for are african dwarf frogs.
So basically the 10 gallon (im sure it is way too small for the fish i have) has 1 big orange goldfish, 1 smaller white/orange goldfish, 3 neon tetras, 2 amano shrimp and 1 small suckerfish (i think a pleco, but it is really small). Sooo I have no idea what to do with these. I want to get more neon tetras since they school but i doubt there is room? The owner has had these fish for a year and a half so they arent in any immediate danger as long as i keep the partial water changes up. Will the suckerfish grow anymore? If not can I add three neon tetras? The tetras arent extremely active as they prob arent very confident. Can anyone give me advice thank you!
