I have an 8" siniperca chuatsi.I bought him at 2" for 30$ as a dat.Hes not very friendly and my kids call him serialkiller because when i first got him i had him in a 150 gal community tank for about a week until i woke up one morning and found 10 dead fish.Including 6 6" redline sharks 3 6to8" balas and a5" moonlight gourami.I just about flushed him but im glad i didnt. Hes grumpy but he tolerates his tankmates.8" lemon oscar 8" redtailed gourami and a16" albino channel cat.
