Ok, here's the deal... I said your tank likely isn't done cycling yet because I thought I noticed you are still having problems with your water perameters, and fish deaths. You also seemed to mention doing a
PWC in your 29 gallon tank, saving some of the old tankwater, and running the filter in the old tankwater for a couple weeks:
"Soaking the filter media in the water i use to do my
PWC s and let the filter run in that water and after a few weeks when i get the tank and fill it up with my new water from my
PWC i want to know if that will be an IC"
....at least that's what it sounded like to me. If that's what you mean, it will not work because the bacteria in the old tankwater will die without an ammonia source. If you mean running both filters on the tank for a few weeks, as I (and others) have suggested then yes, it will work fine. It will not be an instant cycle (you will still have to monitor your perameters) but you shouldn't have any problems- I've set up a few tanks that way and never had any problems.
Now for your stocking options (yes I realize this is for a 29 gallon tank):
"(this is a combo that i want most likely wont work tho)
Shell Dwellers
Clown Loaches
Angelfish's
Yellow Lab
Convicts
Head Tail light Tetras
Betta Imbelis
and
An Oscar( i know oscars are really agressive i read up on them it says this Temperament: BEWARE!)"
shellies- I don't know much about shell dwellers, but I hear they are pretty small and shy so there is no way they could live with either convicts or oscars. Being African cichlids, they also require a much higher pH than the other fish you have listed.
convicts- As a convict owner I can tell you that your other fish would probably be harrassed to death by a convict, ESPECIALLY if you have a pair. A pair of cons would live in a 29 gallon if they were the only fish in the tank.
clown loaches- they're schooling fish that can grow to over 12 inches. Full grown CLs would need at least a 75 gallon tank
IMO.
yellow labs- they're peaceful as far as African cichlids go, but I still definitely would not try it in your tank. They also grow up to 5 inches, I believe, so with the stock you already have there would be no room for them. Also, they need a much higher pH than the other fish you keep.
head and tail light tetras- your tank seems pretty much stocked already, but they are a possibility if you take back some of your other fish. They are peaceful schooling fish that prefer to be in groups of 6 or more, and at this point I don't think you have room in your tank for a group of 6 tetras in addition to all the mollies.
angels- I wouldn't do it, given the fact that your tank has a pretty full bioload and isn't very established. They can also be aggressive and may harrass the mollies.
betta imbelis- not sure... is this a different species of betta?
oscar- absolutely not. Oscars are large aggressive cichlids and can grow up to 14 inches I believe. The minimum tank size for a grown oscar would be 75 gallons
IMO and that would be pushing it. I wouldn't recommend growing out a baby oscar in your tank either- once it got big enough all your other fish would simply be lunch.
Look, I'm not trying to have an attitude toward you so please refrain from doing so to me. I'm only trying to help you, and your fish, out. 8)
