As the title asks. Can I have multiple tailspot blennys in one 90 gallon aquarium? They are small so maybe? I herd blennys are not nice to each other. Are tailspots any different? Thx

I personally wouldn’t do it unless you got in a bonded pair.As the title asks. Can I have multiple tailspot blennys in one 90 gallon aquarium? They are small so maybe? I herd blennys are not nice to each other. Are tailspots any different? Thx
A 90g is a 4’x2’ tank, you are correct - I think this is also what a 80g tank is but I’m unsure if that’s 4’x1.5’. It’s interesting you had that experience, Ive never tried to mix blennies that weren’t barnacle blennies or similar.Blennies are territorial. However, they are indeed small and don't use a lot of space. I bought 2 of them a couple of months ago. Within a few days they were MIA and I couldn't find them anywhere. Turns out they lived happily together in a tiny sump chamber for 3 weeks without creating a crime scene. When I got them out, one of them settled in nicely and the other kept being chased around by my cleaner wrasse. He started spending a lot of the time around the overflow weir, so he's probably in the overflow chamber or sump again.
The one in my DT has 3 different holes and he spends 99% of the time around these holes. Very rarely will he venture out in the open. He probably uses an 8'' by 8'' area. This one's still tiny though. I remember the same behavior from my previous tailspot, although he did use a little more of the tank when he got bigger.
If you have plenty of rockwork and sight breakers I don't see any problems with adding 2 to your tank. You'll need some height in your scape so they won't see each other 100% of the time. If they don't get along they'll both take residence on either sides of the tank. I've kept a tailspot with a bicolor blenny before and they didn't like each other one bit. They never fought though, only acted tough to one another every now and then.
My experiences have been in tanks < 4' in length and I suspect a 90 gallon tank will be at least 4'.
Just so you guys know, there are non-standard tanks that are 90's that are 3'x2'x2' But the majority of them will indeed be 4'A 90g is a 4’x2’ tank, you are correct - I think this is also what a 80g tank is but I’m unsure if that’s 4’x1.5’.
