Think I can fit a peacock eel in here? Always possible upgrade but I'm talking as of now. 40 breeder with 2 albino Cory, 1 emerald, 1 panda, 2 julli, and 2 pepper cats, an electric blue acara and a guiancara Sphenozona. Have a aqueon pump, and 2 aqua clear 70, rated 300 gph. Thanks ahead!
I wouldn't suggest it, your smaller cories might be in danger.
Also, cories really need to be in groups of their own exact species- they can tell the difference, especially when there's a size/behavior difference like between emeralds and Juliis.
Thanks everyone for the replies! Sorry have been working a lot. I will keep an eye out for my smaller, smallest "julli" cories. They are about 1.25 or 1.5".
