More than one Blenny

[Matthew Cautero]

I currently have a tail spotted blenny and was wondering if i could add a Starry blenny Or would that cause problems. I have a 100 Gallon tank with plenty of hiding spots

You could add several different blennies together in that much space. Just not multiples of same . I’ve always had a Midas and bicolor together. Fun to have several

Starry blennies are more aggressive than midas and bicolor blennies. The fact that the stigmatura is in first helps. But in a tank with a 48"x24" footprint I've had starry blennies behave aggressively, not just to other blennies, but to other perching fish.

Same here; starry, molly miller, etc. can be aggressive toward similar shaped fish. Maybe a fork tail or kamohara blenny which are peaceful and also have advantage of being captive bred.

In the same size tank, I’ve seen my starry aggressive to any fish I add that’s bigger than him. Not smaller, ONLY bigger. Regal tang? Foxface? Niger trigger? Lineatus wrasse? All attacked by him. He is one of the most aggressive fish I’ve ever owned and I really would not have expected that from a blenny.
Before the tang police come, I know a regal doesn’t belong in a 4 foot tank. I took her in from someone else who had a 30 gallon and it was in really bad shape. My choice was either put it in a tank it’ll outgrow in 4-5 years or let it die.

+1 If you'd like a blenny that is active and swims throughout the water column versus a 'percher', definitely worth looking at one of the fang blennies.
