Can I add one more fish?

[jake760]

I currently have a 1 year old Fluval evo 13.5 with a pink streak wrasse, yellow line cleaner goby, and a Yasha goby pistol shrimp pair. The Yasha goby sits at the cave entrance, yellow line perches around and the pink streak cruises around. Is it a bad idea to add a white banded possum wrasse I’ve been looking for one for a while and finally found one. I also have a 25 lagoon with one bangaii cardinal but already have a shipment of 2 other fish coming in in a couple weeks. This fish has been hard to find so I want to get it before it sells out and I can’t find it again.

For a 13.5, yes that feels tight. In a 25 with 3 others, I would consider it but it would depend on the other fish and layout.

Though they are shy or borderline secretive, they will come out at twilight and are pretty fast/agile, so even at a small size, having a good bit of rockwork for them to cruise around is probably helpful.

25 has a bangaii and in like a week or so I have a geometric Pygmy hawk and a yellow assessor arriving. I have a good about of rock work in both tanks. I just don’t want to add it to the 25 at the same time as the 2 others and overload it too quick so trying to figure out if there is any possibility on getting it before it sells out

The 25 lagoon would be a better idea, depending. I think that Evo is pretty small.
