There are only 2 endi's in there, my largest bichir is my guinea lap at 21". I have a 2.5ft footprint so no issues with turning. Generally, I feel bichirs do quite well in crowded tanks. I at 1 point was keeping 21 pcs in this tank. But I came to my senses and sold more then half of them off. But while they were with me, they still did very well, growing and putting on weight with healthy appetites. The key was good water. It's expensive and a lot of work but well worth it.
