ROSS said:Lot's of gravel equal lot's of wieght .... depending on method of filtration( hang on back or wet /dry) gravel is an option , mere decoration.. but!!, you'll never see a bare bottom river or lake ! .. so a lite layer mabe half to quarter inch ... again what method of filtration are going with??? I would assume large sump/wet dry system correct me if I'am wrong...
also size of gravel is a considration ,it's risky to put large fish with small gravel they can get impacted ( swallow substrate) and die ...
and color, what ever is clever for you , but IMO blaze orange is a no no ..your fish will have trouble sleeping because it's so brite...![]()
good luck![]()
i was under the impression that sand or crushed gravel was the prefered method for bichirs. i was going to go with the smallest smooth gravel i can find so the fish wouldnt get any stuck in there system. i am going to stick to natural colors... hopefully i can find something darker rather than lighter colored. and you are correct about me using a wet/dry sump. the substrate will mostly be for decoration.
thank you all for your input. i believe i will start with the idea of 100lbs and see if i like the looks of the depth and add more if necessary.
once again thank you all.
