Not sure if this is the correct forum - please move it if there's a more appropriate one. I've never "upgraded" to a new tank. Due to the size of my apartment, I'll have to get rid of my old 70G immediately and replace it with the new 100G. The 70G will eventually be too small for my cichlids so the upgrade is necessary and I'd rather do it sooner than later. I have some questions as I never migrated before. - I intend on continuing to use my 70G filter (the current one I have) in addition to another filter. What size should the second filter be? A friend of mine has a 50G Fluval filter - would this make sense or should I aim for a 30G so it all equals to 100? - In my current tank, I have soil under the gravel in only one part of the tank. In my new tank, I intend to use soil all over (with gravel on top) and plan to do some aquascaping. Since my friend is picking up my current tank tomorrow (as I literally have no room for it - I live in a studio apartment), will it be ok to transfer the fish over to the new tank a couple of hours after planting everything? How risky is this? - Can African cichlids (the peaceful ones like a yellow lab) mix with 2 quite peaceful red parrots that are about 6 months old? I realize the latter isn't African. I also currently have catfish, 4 serpei tetras (I'll add 2-3 more tomorrow), a swordtail and a gourami. - Any products you'd recommend for migrating that I might need? - Are there any plant fertilizer options other than the tabs I got that say they contain ammonia (what the heck?) Any other suggestions would be GREATLY appreciated. Please keep in mind that I am 100% new to migrating and am asking for advice here so if I asked a stupid question, go easy on me! I'm here to listen and learn!
