Witnessed my two smaller bichirs, one ornate and one palmas polli both rub today. Swimming along and then turn sideways and rub on the sand really quick and somewhat violently. Water params are normal, temp is 80, theyre currently housed in a 72 with a handfull of dither fish. No other fish are showing signs of anything. Any ideas as to what could be the issue? If it was one bichir once that wouldnt bother my, but I've seen one do it twice and just saw the other do it for the first time.
Other notes, only live they get are earthworms. The tank is equipped with a UV sterilizer. This perticular tank has been running for 4 months.
