I ordered my shrimp plant from an online nursery. (stock picture at link if it shows up). It's not growing very fast. The cats stay away from it because I sprayed it with bottled lemon juice. It's about 8 inches tall, and has the original shrimps (which are actually brachts), but no new growth. I have it 10 inches below the 60 watt grow light bulb in a lamp. A couple of the shrimps have fallen off overnight. I water it well, when it gets dry, which is about once a week, and also fertilize it with Miracle Gro Blooming Houseplant food, as instructed on the bottle. I've had the plant for about a month. It was in a tiny cardboard pot, root bound, so of course I transplanted it as soon as I got it. I've read that these are "fast growing". Am I being impatient that it's not growing? I usually have a "green thumb" but don't know what to do about my shrimp plant. It's possible that it needs indirect sun, but I have a small apartment and no place for that. Maybe it's just supposed to grow outdoors only and will die. Anyway, it's an experiment -- I had to have one!!!!

Here is a link to the plant in the database... Shrimp Plant (Justicia brandegeeana)

It may be that the lighting is insufficient. I've only known of these growing in landscapes here in Florida, though the data does say that they can be grown in containers.
Just not sure about growing/thriving as a houseplant.

If you've only had it for a month, I think it's still in recovery phase from traveling in a box & being repotted. The fertilizer might be too strong. Less couldn't hurt but too much fertilizer can be toxic.
