hey, hows the hemibagrus doing? any idea of the species yet? i did remove my wyckii's hide a few times mainly so i got too see him, aggression either way is pretty similar and i always have the at least a few fish with ripped fins so dont expect a peacful tank, your oscars may be a bit delicate when yours decides its reckoning time, midas and butti never give up where as an oscar will swim on its side in the top corner if it feels beat. the only bottom dweller that can hack my fish is an unusually aggressive gibbi, currently looking for a home for my 10 inch irwini due to this. my guy is heading for 19 inch now but they are quite slender in comparison to rtc so i think he will be fine in my dd 300 for life, i dont expect him to ever pass 24 inch and im yet to see a tank kept fish pass this mark, have you tbtb?
heres a video, they are quite interesting regularly rolling on there back and are interactive although not very active with the lights on...
jag and butti are now sold.
