Hey guys, I have a few issues regarding to the little fishies I have in my aquarium, hope you guys can help. thanks in advance for reading such a long post :cofn:.

2 heaters

In the tank I have:
Corydoras
Guppies
Minnows
Otocinclus
Bristlenoses
(had swordtails)
Apistos
No fish had ever died on me ever since the establishment of the tank (other than one guppy, who only him and God would know how he was able to jump out of the closed lid and died). :dunno:
So leading on from the statement above, the issues start occurring......
issue 1) couple weeks ago i bought a pair of swordtails (1m, 1f). they were a bit slow, but eventually adapted to the environment and got a lot well with others. a week later, i found the female dead after coming home from work (i don't know what cause her death as she was fine in the morning on that day before i left for work. This morning (04/06), same thing happened, the male was swimming around looking all good. I left the tank for 30mins and when i came back, the male was on it's side 90% dead, struggling to survive, he swam for 2 secs and back down onto the gravel on its side (before i could even go grab the fishing net downstairs, he had passed away.
so what could'v caused the death of the swordtails? are my new pets in issue 2 has something to do with his death? (female died a week before the new pets were put into the tank. Male died this morning after a day or two adding in the new pets)

issue 2) A.Macmasteri Cockatoos (I was told they were anyways). So I added a pair of these a couple days ago, was told that they are quite young aswell. I did some research and in my conclusion, these fish (apistogrammas) are as hardy as they will ever get out of small cichlids. they are doing great so far, but then i have realised that the male has started flaring his fins a bit every time he gets around the female and tries nipping her (he'll give up and swims away after a few tries). is he hassling her? or is it a sign of him wanting to breed? are they old enough to breed? (males colours are slowly getting brighter and more of it where the female were white, but has now shown a sign of yellow tint to the body). one thing I also realise about the apistos is they sometimes when they are still, they tilt a little (like the image of the two female and male apisto, last pic...the male is slightly tilted), is this behaviour normal?

Also just a side story, my two SMALLEST guppies tends to hassle the apistos quite a bit at the beginning but has since slowly died down. (I snapped one of them which seems to being nipping it) <-- strangely, this guppy tried nipping the male swordtail too.
smallest guppies didn't want to leave them two alone

Issue 3) White Cloud Minnows, When I first got them many weeks ago, they were all small and slim. I have 10 of them and about half now seems to be big and fat. So i wondered whether I have a mix of females and males and therefore the fat ones could be pregnant females. could it be a possibilty? 3 or 4 of them has been fat for a few days now, others seems to be at the same size being slim and small.

Issue 4) Otocinlus, I have 3 of these in the tank (all were small, short and thin). I had read somewhere on the net saying if they go big and fat,they they are a healthy oto, but i don't believe that, lol. one seems to be getting bigger, the other two show signs of grown BUT its nowhere near as big. the body width is like a cm wide =.=''. is this normal?
