Hey I am really considering ordering a group of these for a species only 55g. I was wondering if anyone had any experience keeping them. I have done quite a bit of research on them and it seems like they are the hardiest gymnogeo very easy to spawn and able to be kept in a consistent temperature tank. Is a 55g tank appropriate for them? how many should I get for it? what m:f ratio? also would love to see some pics of adult specimens that some of y'all are keeping! thanks.
