yeah i know the GSP and F8 require BW as adults. like i said i am upgrading to at least a 75 when i move out in a few months, but until then im taking my chances that everyone survives. the congo was too cool and too hard to find. but once i move the congo will stay in the 29 and the F8 with the GSP will go into my 75+, whatever i go with. i did plenty research and i know the risk of the congo killing everything else. but he is very docile, i watch him very closely when i get home from work every night from a far so he does not know i am there and i see him swimming around, he swims around the other puffers not even giving them a second look. the pleco i have was even eating his algae wafer on the sand right next to the burried congo, also hasnt messed with the red crab i have at all he eats the hell out of the ghost shrimp though. please dont assume that i dont research my stuff before i get it. i worked in a pet store for damn near 3 years and i know puffers and their natures. and by the way, my F8 and GSP i started to turn slowly into BW, there is a very very low SPG in the tank and the congo is doing just fine. i dont plan on going any further BW until i move and get the congo out of there. but like i said putting him in there was a known risk i was willing to take. i did plenty of research, i went into the pet store not intending to bring him home because of how aggressive congos are. he just hangs out burried and chasing ghost shrimp, he doesnt seem aggressive at all, i know i cant go by that just yet, but he just seems very docile.
