Aquaponics - Fish types ?

[iHigh]

Hi

Besides Telapia, and stuff live gold fish, what other fish can be used in an aquaponics setup.

Would it be possible with Cichlids ? or other more exotics like Discuss ?

Wait, so you cannot use any fish for aquaponics?

 

The GF keeps bugging me and wanting to get a Siamese fighter, put it in a bowl and then stick a plant on top of it and I think the fish will die cuz I have no clue what to do so have been against it.

Think the PH and water temp limit fish choices.

I wanted to do something intergrated into my marine tank, but the salinity is a problem.

You are limited to tilapia, koi, other carp for summer aquaponics. Koi are hardy fish and can be monetized. Raising baby koi for the industry and such.

Trout is good in winter time with much colder water temps.

The problem comes flowering time when cannabis P and K needs change. There is generally not enough P to push flowering.

Always wondered this. Have never seen a proper aquaponic cannabis grow...

Aquaponics is awesome but not really suitable for cannabis.
The plants will grow, but the yields will be low.

Research the ''nitrogen triangle'' in fishkeeping and you'll understand why@Totemic mentioned P and K.
The main problem is, you can't add any ferts or you will most likely poison and kill your fish.

True closed loop self sustaining aquaponics systems are good for growing mostly leafy green vegetables or plants that don't have varying nutrient requirements.

Okay, so maybe keeping a mother or two, in veg, over an exotic tank might be possible ...??

All African Cichlids should be kept in water with a pH of 7.5-9.0, a water hardness from 10-20 dH, and a temperature between 77-82°F.

The actual ranges of the African Rift Lakes are:

Lake Tanganyika — 7.8-9.0

Lake Malawi —  7.4-8.4

Lake Victoria — 7.2-8.6

Your choice of fish species will be a determining factor.
Exotic fish can be finicky and some fish don't play well with others-territorial to the point where they will kill or eat each other. Not sure if one or two fish in a tank will produce enough nutrients to sustain a plant.

The ideal pH for discus is around 6.5. If your pH is over 7 or below 6 it may begin to cause discus stress. Tank bred Discus species have been known to thrive in pH as high as 7.8 as long as there is little/no fluctuation. Relative water hardness should be 1dH - 8dH.

I am thinking a discuss tank, with some plants, and neons....tank will have to run for at least 6-12 months before it would be stable enough to add plants on top
