Hello Kevin

I am very interested and have always been fascinated by a tank full of aquatic plants and perhaps a dozen or so tetras! I have read that you need a CO2 injector as you mentioned but they don't come cheap!

You stated that there is a DIY way for the CO2 thingy. Care to elaborate? I would be really looking forward to meeting up with you in Dec and discuss all these issues. So much to learn from you. I really like the underwater world a lot and that is why I am fascinated by beautiful green plants in an aquarium.

All advice appreciated.

PS. I must admit that the flowerhorn has gotten to me as well. Guess you could say I've been bitten by the Luohan bug! I have to agree with Eugene, TonyG (nice to see you here as well) and the rest in that the luohan cannot be classified seriously as a cichlid due to the numerous cross breeding. I am surprise that it hasn't been sterile! We don't get as many choices of other foshes as before because there is less profits to be made, I guess!
