Damsels don't jump, but a lot of people don't like them, sometimes they are aggressive, but there are lots of different type under the damsel name, and I personally never had difficulty with them. Chromis, are small and don't jump, they like to school. Clowns don't jump and have a waddle-like swim. You should check out a web site for aquarium fishes, click on a picture, it will usually give you a pop-up about the fish. Hope this helps..
in a small tank any fish will jump. they are just not used to being confined so when they bolt they run out of room and just end up going up. the larger the tank the less likely these jumps are to occur.
Ive had alot of jumpers over the years. Even out of my 150 gallon which has a glass top and only small space in the back.
I had a blue hippo in there for 8 yrs and in summer had the front glass off for heat and it jumped out. Ive had clowns jump angels jump and everything in between lol and I don't even have open tanks as my lights sit on top. Alot of them I had for years before they jumped.
I'd say every fish can jump but some do more than others like twitterbait said.
I had an open top tank with tangs chromis clowns lawnmower blennies, dragonets, grammas, assessors, for a year and NO jumpers.
then I had a COVERED TANK and had like three or four different fish jump out. So my point is, its just a gamble.
I went to home depot and got the eggcrate and cut it to fit the tank, that way it lets heat out and keeps most jumping attempts thwarted but still lets light in. no, it wont overheat. but with a small fish or opening, theres always a chance of jumping. the fish have amazing aim to project themselves with fighterpilot accuracy through a hole no bigger than their body. its disgusting.
My 220g has been up for 2 months now and I have already had 2 jumpers. Luckily I have the calfo style overflow, and a CLS made of 2 inch pipe that covers the whole backside of the tank, so they have nowhere to go but the overflow. My 6 line is living back there right now. (cant figure out how to get him out!)
