I bought what I thought were six bleeding heart tetras but it turns out that two of them are different. They don't have the red spot "heart". They are more light rose colored than kind of greeny yellow and the coloring around their eyes is different. Their dorsal fins are differntly colored as well. They seem to school all together, though. I am thinking that the two might be white fin rosy tetras. What do you think? Pictures... The first picture is one of the bleedingheart tetras and the second picture is the two that don't look like the other four. That last picture is one of each.
