When you say jumbo how big is jumbo ? I know sometimes places use the term jumbo when selling the fish , but in reality it don't meet the term correctly ?
For example :
I consider my yellow stripe maroon clown jumbo , she's over 6+ inches in size and about a inch thick body girth and she is still growing now that is jumbo . she has a nem about 10 inch in size and it's just a little small for her.
In the past I did get to see 2 supersize jumbo's in on of the shops I visit , they both were close to 12 inch in size , kind of makes you think ..
when I got mine they were the size of my pinky finger nail , now the female is 6+ and still growing , the male looks like a baby and both are the same age , he is about a inch and a half in size yes tiny .
now you can see why I asked . because I would hate to see you get a nem that is to small for your clown that she will upset , causing it and it hides in cracks in rock work.
a nice bubble tip big enough for her would be a nice choice .
You may want to somehow confine your clown till the nem settles in and gets a good foot hold . as you don't want your clown to mess with it before it seats itself .
I hope you get to enjoy your clowns as I do mine , sometimes they can get under your skin constantly moving things you placed ,
I consider them my kids
this thread can tell you a lot about clowns and there habits enjoy
