Towards the end of the year I am upgrading from a 30 gallon to a 55 gallon, I am wondering if I would be able to keep a new juvenile rainbow shark in the 30 gallon then transfer it to the 55 gallon when ready.
 
Well, it depends on the size & shape of your 30g & other fish you have or want to add. A tiny shark, 1-2 inch, should grow almost to adult size of 5-6 inches in a year with good care. They tend to hate & harass any torpedo shaped fish & many bottom feeders like corys & small loaches...even in a 4ft tank. You might be better off waiting until you actually get a 55g...Oh & watch out for jumping in a less than 4ft tank...

It is a 3 ft long rectangular tank, I currently have a small shoal of Buenos Aires tetra which apparently are compatible with RS, the juvenile I am looking at getting is around 1 1/2 inches and the tank I’ve got now has caves, bog wood and artificial plants(so BA tetras don’t eat them) I should be getting the tank in a few months time.
 
I haven't kept BA tetras but if you don't have many other fish & you are truly sure you can have a 4 ft tank by then, I'd say it would be ok. Lots of hiding places , at least 3 different 1s, help a lot with sharks.

I always prefer live plants to artificial. Things like java fern & anubias are pretty sturdy & easy to grow in almost any light. Try them! Your shark may like to graze on them (or the stuff that grows on them)…& so what if your BAs nibble them a bit? Both plants, of several varieties, are attached to wood or rocks with sewing thread or gel super glue. Plants can help with water quality & territories, neither need fertilizers either. (OK, I belong to a plant club nowadays but really, live plants can be easy & look so much better.) Try at least 1 of each, you won't be sorry!

Ok thanks for the advice, I’ll try out some different plants and see how it goes.
