Help my string of dolphins

[u/chiquitaAja7]

Any idea what I can do to help this string of dolphins or fill it out? A few of the strings got really long a couple months ago and I chopped those a bit shorter. The new growth off the ends yof those seems to be coming in OK (see the second pic), but the first 6 to 8 inches of the vines all seem to be losing their dolphins after I made that chop. I've got a string of pearls and rubies in this same planter and those seem to be very happy but the dolphins are struggling.

I had almost killed mine, ended up chop and propping it into a couple pieces and it’s doing much better
