I bought a pair... Henry told me they are Scorpian Blenny also but they look like Red Scooter... The one that you have... The only difference... They dun pair up... Like mine lor though one male one female...
Oh... Okaie... Heng.. I haven go and buy the pipes... LOlz... Thats mean the water level in the tank must be over the second bend to start the siphoing... Right???
Oh... That means when starting the siphoning... The air valve will be open bit by bit to extract the air... and when the water start flowing to the sump... the air valve have to be closed... Correct interpretation???
Think you got a Stonogobiops xanthorhinica... The dorsal fin doesnt seem bitten off or what... My Stonogobiops nematodes also become Stonogobiops xanthorhinica because of fin rot...
