Latest updating of my Common Octopus

[OctopusChan]

I noticed Oct Paul is an vulgaris too ？
They look the same.
During the 30 days my oct have gained about 20% on weight.
He really eats a lot.Even 13 crabs in 2 days once.

As the system of my tank is not strong enough. NO3 and PO4 may become a problem.

Yes, Octopus Paul was also a vulgaris. It may help to do smallish daily water changes but eventually, he will outgrow your tank's ability to cycle his waste.
