Alot Of Questions, Insuring A Proper Re-cycle, Also Agressive Fish Att

[MisterTickle]

Okay so heres the deal, I started my tank last year and have been through quite alot of different fish and such. I had last used Bio Spira which to my knowledge would cycle the tank with introduction of fish, I think I had added 1 Red Parrot (or devil or whatever), 1 Gold Sevruem (Almost impossible to find at the size It as, Damn its my favorite fish aswell), and two Kissing Gourami's. One of the gourami's is still alive, Which is pretty cool. I went through a few fish after a few months of cycling problems, ich and such and finnaly I had ended up with a Red Parrot, Two Scavengers (Which although two different types, Group together in the back left corner), A "Bottomedweller" fish and that was it. It stayed like that for a few months, My other gourami had went but everything was alright. I honestly regret letting it go but my fish were fine but I had made a pretty dumb mistake. On my "Aqua-Hobby" re-investment ditch I ended up taking out like 70-80% of the water which made me realise shortly after, That would probably affect the cycle of the biological filter. I had added in some Waste Control, A thing that clears cloudy water, and some Preventivie Ich Treatment I always use (Which seems to have kept my fish from getting sick luckily) and left it there for a few days, Oh and to mention I had exposed my heater to air and it began to burn so I had to buy a new one so a few days later I took a trip to my LFS and I decided to start leaning more towards the agressive side and purchased two agressive fish, I'm not sure of their names and would like you guys to help me get their names, along with a new heater and a thing of cycle. I poured 3 capfuls of it in with my new fish, after floating it there for like 30 minutes and letting the heater sit in I turned the heater on (Leaving it on default settings as it says to) and let it run, releasing the fish. All the fish seem to have adjusted fine, Over the next 5 days I've been feeling them once a little bit after I wake up and once I go to bed for like 4 minutes, Usually all the food is gone when I walk way but a few pieces may stick on the ground but my scavengers and such always get them. So last night I decided to check the water and I got a Amonia reading of nearing 2.0, Maybe 1.8-2.0 ish and the PH was 6.0, I decided to leave it overnight and check it and today the same readings. I'm not panicking too much as I know my biological filter is being reestablished pretty much and I hope things will stabilize, So I added some more waste control and cycle in there to hopefully speed up that process.

Now regarding my Bottomdweller, Which is bigger than my gourami. All my fish seemed to be okay with each other. I am aware that my Gourami will probably have to be moved to another tank that I may set up somewhere or bring it back to my LFS. My Red Parrot always chased my bottom dwller but he was fast and didnt let him get him and it wasnt very persistent. I'm noticing EVERY one of my fish INCLUDING my supposed not so agressive Gourami attacking him, He also seems slugish. I don't understand why suddenly every fish, including one not known to be very agressive (Gourami) would gang up on a fish every time hes near them. Could he be sick? I mean, Why wouldnt they all go after him yesterday or tommorow but why today does all of a sudden hes the one to attack? Any suggestions on my tank, Things I may have done wrong or things I could do better?

Here is my tank, Its a 29 gallon, I would like someone to tell me all the names of my fish I have for better referenced, Thanks for your help.

Edit: I am also aware alot of my fish will grow bigger and am hoping to find a place to put a bigger tank.

I would copy and paste this thread over to the cichlid part of the forum.
All you can do is water changes and increase aeration,.
