Hello, has anyone had any experience keeping geophagus sveni successfully with diamond tetras? I feel they're pretty tall bodied but would probably fit in the geos mouth. I have 7 adult sveni with 5 rummynose and 5 angels in my 96x30x24, 300 gallon. My LFS has diamond tetras on sale and I've always appreciated their look. I just wouldn't want them to be lunch for the sveni. Thanks in advance.
