How many should I get?

[Aqualoon]

I know, the age old question of how many.

Tank size is 125 gallons.

I have a local who has Ikola and then getting some Red Rainbows and Ikonde shipped from a breeder - how many of each should I get?

Diet question - Getting fry sizes of 3/4"-1.5" which NLS should I be feeding? (Growth, Regular, Thera A+, Algae Max, etc.)

I have a mixed Troph's display in a 125 gal...7 Maswa, 10 Moops, 11 red bishops, 11 Moliro, and a few other tangs & Malawi friends...total number of fish is 48 ranging 2"-7". If you plan on just Troph's I would suggest 15-18 of each of your 3 variants...that way if you ever decide to go species only for breeding purposes you have a decent sized group of each to work with...or to sell on as a breeding size group of you change things up.
I personally don't like NLS FOR Troph's...had a bad experience in Australia with it, plus it leaves a kind of rust colored rresidue...i used baby Dainichi veggie fx for my 1"-2.5" fish. I use YFS soft spirulina & YFS green supreme, omega one kelp pellets for my sub-adult and adult fish 👍

I would think that 45-50 total would be fine for now. But as they grow you will need to make sure to keep an eye on your nitrates every week and adjust your weekly water change schedule accordingly. So that your nitrates don't creep up on you.

Thanks for the replies guys, going to start out with 50 and see how that works out. Really excited to start stocking as Tropheus have been a fish I have wanted since I started in the hobby but back then didn't have the room for a sizable tank.

In the past my maintenance schedule was twice a week, not so much because I had high nitrates, but I find working on my tank a de-stresser from work.
