would a Midas blenny and a clownfish pair work in a 20 long (30 gallon’s length of 30 inches and 12 inches width, just loses some in height). I’ve seen people say they need 30 gallons but a 20 long has the same length and width as a 30 so I’m not sure now. Plus I remember asking another question like 7 months ago and someone said they had a Midas in like a fluvak 13.5 and that it’s just fine. The 20 long I have has lots of rocks and I’m willing to get barnacles if need be. Just for a fish that perches a lot, height wouldn’t be too big of an issue right? It also has an oversized filter too incase anyones worried abt bio load.
