Thanks for looking! Honestly I can't answer about the different challenges between the typical and this one. My past tanks have been 32, 29 biocubes and other smaller tanks. The biggest challenge I foresee with this is getting to the bottom of this this to clean. I have a 3 step stool, snoorkle and mask! The two 3ks are providing excellent flow so hopefully future uglies will be easier to deal with.I am thinking I am coming around to half circle fish tanks! looks great, is there many challenges having a tank like this one that wouldn't occur with the typical rectangle? Great job, I will be following along!
