Good morning,

I have a Marine x 90.3 It has a 60gal display and I currently have 2 clownfish, 1 bangai cardinal, 1 fairy wrasse and a firefish. Im kinda thinking about a starry blenny or midas blenny in the future but I dont wanna he pushing it? Do you think this is a reasonable stocking for a 60gal? All my fish now are very peaceful the most "aggresive" is the bangai cardinal but he just likes to chase.

I think that you will be fine too! FYI, starry blennies tend to be more aggressive than midas blennies but I think either would work. I love my midas!

Adding a blenny to the mix would be perfectly fine!

Btw you can get away with both in 60 g, they have different ecology and behaviour. Just make sure you have hiding places for both of them, like a hole in the rock, amphora, worm tubes or other stuff.

And to the love of god, remember that midas blennies are planctivores and don't eat algae and starry blennies are omnivores and need both meat and algae (starries ARE NOT herbivores like tangs). I've seen too many people putting midas blennies for algae control or getting starries and lawnmowers in new tank without algae and not feeding them "so they fill help with future outbreaks". Starries are not herbivores, but they need fiber. If your's will be getting too fat, it means it ate too much proteins and fats, got constipated or bloated, so leave more nori for it. In the wild more herbivorous blennies constantly graze on algae for the detritus and microfauna found inside it, so they have big bellies adapted to process lot's of low calorie diet. These bellies can store a lot of high calorie fat protein foods, but it doesn't mean it is good for the blenny. They often die "for no reason" and people are dumbfounded that their "fat" and "eating like a pig" fish died of organ failure because of only mysis and brine diet.

Keep your blennies healthy and enjoy your time with them, they are the best fish this hobby has to offer!)

I appreciate this comment Ill make sure to have nori available for him. They are such pretty fish! Has he been mostly friendly? My only concern is I have a blue chin fairy wrasse which is friendly but I had a bicolor blenny that I had to move because he was attacking the wrasse.

My blenny is a young female)

Big Salarias blennies or lawnmower blennies are only agressive to new additions if feed rarely and in small tanks and even in such situations they quickly stop being aggressive. I know, because i kept my starry in 15 g for a few months until i started my 30 g. Although i fed her a lot she had not much space and harassed a damselfish pair when i put them in, but quickly stopped biting them after a few minutes and they lived fine after.
They won't harass an existing fish, unless it's a similar shaped blenny(exception is male*female pairs in very large tanks), and even considering that midas * starry is a common combo because they are so different. But i still would probably stick to 1.
In my 30 g she hadn't attacked any new fish. I even say more. When i added a sixline(which i rehomed), she protected her from damsels!
Blennies are really chill overall, so don't sweat it) Once again i would recommend buying some hiding spot for it, like an amphora or a shell. They look very sweet when sitting in their homes )

Ps: bicolors are jerks, it's true. They are not irredeemably evil like some big damselfish or triggers, but pretty comparable to chrysiptera damsels i have. Small, feisty and bi-coloured... My bicolor also hated my anthelia coral and started biting it for no reason (not even eating), so i rehomed her(yeah my luck with blennies was that i mostly get small fish and they turn out to be females. The only male reef blennies i had was a tailspot that jumped out. He had a beautiful crescent tail...)

That pic is just too cute! I love my blennies as they really do have the best personalities!

Tailspot blenny forsure, very personable and peaceful. If you got more space and want a active fish, try a yellow coris wrasse too
