Opinions On Possible Stockings Needed

[Jaded12]

On friday I'm going to begin the construction on my fish room And once I get that going I'm going to begin setting up my tanks and such, most of my tanks are establish and will be moved from my bedroom and my boyfriends house into the fish room, but I have 3 empty tanks that I'm not sure what to do with, here are my stocking thoughts, please let me know what you think.

75 Gallon (Freshwater)

1 -(L - 66) Gypsy Kin Tiger Pleco (Peckoltia sp.)
5 - Nanus Cory Cats (Corydoras nanus)
10 (2 males, 8 females) - Lyretail Guppies (Poecilia reticulata)
10 (2 males, 8 females) - Topsail Platies (Xiphophorus maculatus )
15 (5 males, 10 females) - Hi Fin Lyretail Swordtails (Xiphophorus helleri)


90 Gallon (Freshwater)

2 - Neon Blue Discus (Symphysodon spp.)
2 - Snow White Discus (Symphysodon sp.)
4 - Cherry Fire Shrimp (Caridina serrata)
6 - Diamond Head Neon Tetras (Paracheirodon innesi)

why not go for a nice S. Piayra? Only one or 2, and in the 90, but they are the god of piranhas!

I'm more of a fan of lots of fish, lots of activity, IDK, one or 2 fish in a big tank just isn't my thing.

Anyone?

The stocking sounds great apart from the 6gal, i would only have female guppys in there, wouldn't have males unless it was a 10gal because the males can hassle the females a lot (even in well balanced male and female stocking groups) and simply females just need the space of a 10gal or more to be safe enough around the males.
If not guppys though, i would go for endlers- you would be able to have a mixed gender group with those, and although the females are very bland looking, the tiny males are very beautiful (they can also crossbreed with guppys too, so i suppose you could have two female guppys and a single male endler).
Either that, or i would just keep the 6gal to a quarentine/hospital tank, which can be a very valuable addition to any fishkeepers tank collection (especially with guppys, who tend to be quite fragile and prone to desease now days), or even a fry tank or something (a quarentine/hospital tank or a fry tank or both would be what i would personally go for, rather than making it just another standard commuity fish tank).

However, with the 75gal i would choose between either having swordtails or platys. Platys can crossbreed with swordtails and vice versa, they are very similar looking fish too apart from the obvious sword on the male swords.
You also can't have that many males with swordtails as they will fight with each other almost regardless of how many females you have (unless it is an exceptional amount, like 1male per 10-15females). So its best to have just one male sword unless you are willing to devote a vast bulk of the stocking space in the tank to having a massive amount of females.

Once the 75gal is more established (6months+), i would also consider having some neon or cardinal tetras of a shoal of around 8-10, and perhaps some amano shrimp of a group of 5-10 as well. Khuli loaches would also make a good addition to such a peaceful tank set up.
I would strongly advise going for a sand substrate in any tank that holds corys or other bottom dwelling fish which feed with barbels/whiskers as having sand will allow them to feed normally and naturally and is also easier to maintain/keep clean than gravel, which is very important for bottom dwelling fish. If you go for fine silica sand, you can get it in a wide range of colours from natural shades to white, black, blue, green, red, mustard yellow etc etc.

I can't comment on discus as i don't know a great deal about them, but i do know that they are quite fragile/sensitive fish and putting them in a newly set up tank would be a risky move. How are you going to go about cycling/establishing these tanks?
