They are 16" and 18" when I got them as pictured above. After almost 3 months, they have each added 2 more inches and growing. Both are very thick. Now, is someone getting a new larger tank? Perhaps a 250?
What about a black ghost knife? Or a africanbrown knife if you like knifefish, i would get some clown loaches and some cichlids like firemouths, acauras, festivums, etc if i was you, and use bala sharks or silver dollars for dithers
How did you get a Sasquatch skull?! Lol. The o's are gonna eat their tankmates eventually. Not cuz they're aggressive, but because of growth rate. Your oscars can hit 10" in their first year and then some of their mates will be looking delicious. CKF is a great tankmate for them. So are plecos and equal sized catfish.
