I'm sure my bamboo has no effect on the shrimps...
But everyone has different circumstances. I've even seen people grow java fern as a house plant with household humidity.. LOL
No point arguing over who is correct. it is just recommended that you don't use lucky bamboo because it might be unhealthy and poisonous (but heck, it might not be, like in my case). key word? recommended.
But if it does well in your tank it can acts as a good ammonia sink:)
it's just like medicating fish, it's at that dire "medicate or die" moment. use medicine? but the meds contains a known carcinogen? use or not?
Ultimately it's the individual's choice :)
let's all be nice and talk about our own practices.
but don't force opinions on anyone ok?
Choclate, it's better to say, "I recommend that you keep the bamboo leaves above water, because it might rot if you submerge the entire plant"
and so what if no one agrees with you? listen to what they have to say too. haha.
that's the way to keep this place friendly. otherwise people will get very angry at you because you keep trying to tell them that they are wrong :P
