Why do my blennies keep jumping out?

[BlenniesAndTangs]

Strange question, but ive had 6 blennies jump out.

I have a lid, but someone they cheat the physics and jump.

Does anyone know why? I really hate how these poor little guys keep jumping out.

I have a lawnmower blenny that loves to jump out of the water near my return nozzle. I've covered up EVERY opening. There's duck tape where the wires and return go in. Even a little opening is enough for them to jump through. Have no clue how they can get through suck tiny holes but they do. My advice is to get some duck tape and make sure every little hole or opening is covered. When you use the duck tape make sure there's no sticky side pointing down. Last thing you want is the fish to get stuck to the tape. Fold a piece of tape then tape that down. My 2 cents anyway.

Someone said it in an another tread and kind of make sense too that they are living in deeper water and not used to have the surface so close.

I had trouble with Firefish jumping out when I used tops with 1/4" mesh. I changed to 1/8" mesh and problem solved.

Today my baby red spot jumped out, he had slept in a position where the opening was above him (those lid parts to close the opening kept falling in the tank) and there a power outage this morning. All of my blennies that had jumped out has such a happy,affectionate playful personality that they couldve just done it on accident just by hyping themselves up, They probably had no idea what was going on. My bicolour blenny has been with me since March (i got him for my birthday) and he clearly knows because im sure hes seen his friends jump out and now hes just like ''Okay, I'm not jumping.''

I have a 175 gallon tank, it isnt super small.

I guess you still not deeper than 10-20m

Oh, ok. I started doing saltwater tanks on October 2020.

They are just jumpers… hyper and easily spooked and rocket shaped. They can’t really jump out of the ocean and they don’t know jumping is death for them in your tank. A tight fitting lid with 1/4 inch mesh should fix it.

I used to have a Midas that would jump out of the feeding door as I opened it. Hit me right in the face one time lol He was just THAT excited during food time.

First off, I’m sorry. I have a Houdini that I routinely find in the filter floss or sump so I feel your pain lol except he doesn’t die because I “plan” for it…sorta. I would be checking for stray voltage, or current, that could be them wanting to gtfu of that tank.

Nearly all of them got bullied by bigger fish such as my lemonpeel bullying my baby red spot. So they have been forced to swim at the top. Bicolour blenny gets sorta picked on, but hes just a blenny sitting in his 4 totally different holes around the tank, sitting in the filter/pump (not sure what it is) when its off, he's been in 3 different sized tanks.

So you already know why he is jumping then…

That is brilliant! Voltage check? This is the fist time I have heard this adressed. I have felt a smal amaount of voltage from time to time. Usually when I barely nick the survace with my nuckle or something. In the same tank I have had spot tail’s last years, and some days. I’ve allways written those small shocks off thinking this could not be. Nothing in the tank seemed to be reacting to any sort of distress. Now have heard somone else mention it, I will be researching. Thank you!!! Great stuff!!!!
