Pineapples die back after fruiting anyway so you might want to avoid that if you want something that won't die shortly after you get it.

Anyway odds are your problem is overwatering, given that you consistently kill succulents, and not light, because that'll just make succulents sort of stretched out/floppy/pale.

(If you really want a pineapple plant you're better off just starting one by rooting the leafy part on top of a store bought fruit, although this is a bit of a process if you want to be successful, although it's not really hard. I'd recommend looking around online for some tips. Basically though, you don't want *any* fruit around the part you're trying to root, or the fruit'll rot and kill your new plant. Second, rooting hormone helps a lot in this case).

Oh, and I forgot to mention, but aloes are apparently winter growers (although I'm not sure if this is some hard-and-fast rule or what) so watering them a lot in the dead of summer is apparently not really a great idea.

Additionally if your problem is overwatering, you might also be using an overly heavy soil. Straight up bagged Miracle Gro potting mix is usually a bad choice because it's mostly peat, and peat doesn't really behave very well and it's something you probably only want if you have a plant that needs really acidic soil that doesn't dry out very quickly (some ferns seem to like that).

General advice would be to go for potting mixes that half a lot of bark and non-peat components and then mix in hefty quantities of perlite, although there's better, more specific advice if you look around the forum a bit.

Clay pots can also help a lot too, since they tend to dry out and breathe, but at the least do *not* use pots without drainage.

When you do water, make sure you water till water runs out said drainage holes because that tends to carry away a lot of the salt and other undesirable *stuff* that builds up in your potting medium.
