One more fish?

[Troender]

I am planning to put up a 30 G tank, with a 15 G sump for my GSP. Together with the GSP I am going to keep a lawnmower blenny. Is the tank then stocked to its limits, or could I put one more small fish there - if I find one that can go together with the GSP? Marine tanks are out of my element, so I really feel like a noob here.

You are one blenny overstocked, as it is.

if you were to upgrade and get a lawnmower blenny, make sure you have plenty of algae first before getting him. this seems to be common and it has happened to two over the past year and a half that i have owned. they will take to other foods offered and not eat algae anymore which will in turn not give him the nutrients he needs and will kill them over time. they will start to look very fat like they have bloat, i have treated with epsom salt and had no good effect and the fish wound up dying

You could feed it algae wafers.

There are plenty of foods to feed that type of blenny if your tank isnt full of algae. Algae wafers as PP suggested, spirulina, emerald entree, romaine lettuce, dried seaweed sheets and the list goes on.

i tried multiple things, once he started eating flake i was giving to other fish, he would slowly take the algae out of his diet no matter what i did for him to eat other things. i even would feed flakes little by little so that minimal would fall down for him. he just started swimming up to me! then eventually he started eating a little bloodworm and mysis i would put in for some variety for the other fish and thats pretty much when he stopped eating all green stuff. i had algae wafers, dried seaweed sheets, he would eat pellets that had spirulina in them but it wasnt enough. i want to try one again but waiting til my live rocks are waving with algae that im trying to cultivate for one eventually
