Akin to my other post, this is in regards to obtaining a new, much larger tank within the next few days. I currently have an established 20 gallon with 2 ghost shrimp, 1 vampire shrimp and 4 corys. Shortly, I will be getting a 33 gallon or a 50 gallon, not sure which one, as it depends on what store I go to. However, due to my housing and space situation, I can only have one tank at any time (there's only one empty space for tank placement). This leads me to being forced to transfer my fish directly over to the new tank as soon as it is fully set up.
My question is obvious. If I were to use the same media in my current filter, transfer the same substrate, and the exact same ornaments and plants from my established tank, will this provide sufficient beneficial bacteria colonies to keep my fish alive? Should I expect fish loss? Any tips or advice? Worst case scenario, I expect my cories to pull through (these guys are battle axes, survived every hardship and disaster my tank has thrown at them), but I fear the loss of my ghost shrimp and prized vampire shrimp.
I understand that I need to cycle tanks first, but if I do get this new tank, there's no way I'll be able to let it sit for several weeks while my fish hang out in my current 20 gal, there's just no room for it.
Thanks a lot for any help!
