Will this tank be over stocked?

Question
I'll be setting up a 125 gallon (72x18x22) Aquarium later this week, And i was wondering what you thought about the stocking.

X1 Rhino Pleco (Hes about 5 inches right now)
x1 Black Ghost knife fish
x2-3 severums (Hopefully the brown ones, and hopefully either 3 males or 3 females <_<)

Think that would work fine?

The rhino pleco is currently in my 55 gallon aquarium with 4 totally matured filters on it, I'll be moving all those to my 125 along with the pleco, Is that okay? If it is I plan on allowing everything to settle down for a few days and then slowly starting to stock the tank.

The filters have been matured for well over 6 months, So I assume if I allow them to adjust going from tank to tank and not allowing them to dry out, They'll pick up like normal and do their job?

Answer
Hi Lucas,
Sounds like an awesome setup definitely not overstocked! I love Black ghost and Severums.

Moving the matured filters over will be a great benefit for the new tank and should definitely shorten the new tank's cycling time drastically. It should be perfectly fine moving the rhino pleco into the new tank along with the matured filters.

I think all will work out well for the filters! Sounds like a great plan.

Best of luck and I do hope this helps!
