nice pics, as it was already stated, the hides are a bit larger than normal. also, to make ur bp feel more secure, cover 3 of the sides. i used black paper o.O, and it seemed to work fine, but theres also alternatives

u will soon find that keeping teh humidity and temps correct in the glass tank is a very difficult job, doesnt look like u hav a heat lamp which is a great start. i wasted money on red bulbs / heat lamps which only damaged the ambient temps and humidity, and caused not only ME stress, but my bp (went off feed). took that off, and things got better (good shed, calm, etc...)

but yes, security + hide sizes + maybe a little more foliage (bc of 30g tank) + and GL with the transition from live to frozen . i cant offer advice with that bc i havent even solved my own problem. i love mice and rats too =p
