Blue Lobster vs the Java Fern

I have these thriving java ferns in my tank. They're doing so well that I've recently had to separate and replant at least 4 new plants that had grown from one of the 2 original ferns and I've only had these plants for about a week. The other day my boyfriend picked up a little blue lobster from the LPS. The little menace has already snipped of a few of the java fern leaves from the base of the stem. Will my poor java ferns recover from his "gardening" or are they doomed to extinction?
Oddly, I also have 3 banana plants growing in the tank who are also flourishing. The blue lobster has not touched any of them. Between 2 of them there are 3 leaves with stems that are well over a foot long. They have intertwined and made a sort of arch shape and are currently in the process of growing more leaves with similar stems.

Why does he only terrorize the java ferns and not the banana plants and is there any possible way to stop him?

 

Crayfish and plants DO NOT mix. crayfish are like aquatic bulldozers and will uproot anything in the tank. you could try floating plants, but your plants are doomed.

 

Poo...and I was rather fond of my under water garden. LoL

 

my blue crayfish distroyed one of the fake plants yesterday.

 

Bummer! I seem to have a 2-man wrecking team. The little blue lobster my boyfriend has named "Blue Balls" is the clipper and ripper, clipping off pieces and digging up the smaller java ferns. The second half of the team is the just about foot long pleco, aptly titled "Godzilla", who is the smusher and muncher, plopping down on the java fern squishing them and up rooting them then eating pieces of his "victims".
...all this destruction and consumption, yet my banana plants remain intact. Do you think maybe they taste bad because they help filter nitrates from the water?

 

Lol...sorry to laugh but it does sound like you have a deconstruction crew on your hands. If you have an empty 10gal I would put your crayfish in it. They do best by them selfs.

 

Sounds like a good idea. My boyfriend wants to try putting it in a large breeding enclosure, you know the netted basket-like bins mainly used to keep fry in the same tank, but safe from every one else. I don't know if the lobster's going to go for it though. LoL

 

Dont forget they are escape masters! If there is a way out they will find it and try to get out.

 

You make a very good point! I'll make sure we take that into careful consideration.

Very true. However, the smaller the tank the easier it is and the more likely it is to escape. I've not had one escape since I stopped using 10s to keep them in.
