Hello to all! I need help finding the best mix of fish for my future 20-23 gallon tank. I'm hoping to get a long glass. The tank will have a Tetra 10-30i filter, lots of real plants (marimo ball, water sprite, java moss, and so on), heater, and decore. I keep my tank clean and my pwc up (I actually do more than necessary).
The Betta will all be sisters that I'm raising together (they are one month old atm). They are VT and expected to be a little small because of mom's size. I know for sure that I want at LEAST 5 Female Betta and 5 Kuhli Loaches in this tank. I also know that besies Bettas and Kuhlis, Otos are the only other fish I would add to the mix because of their cleaning ability and small size.
So my question boils down to numbers. Considering all the factors, how many Betta and Kuhli can I keep in this tank? Also, should I include otos and if so, how many?
*Additional Question: What sand substrate (type and brand) would work best with this setup?
If I remember correctly, you should keep kuhli in groups of 6 or more and ottos in groups of 3-5. For Kuhli, I would definitely use sand (all seems the same to me) but because of that you may have to compensate for plant nutrients with root tabs and/or water column ferts. You may only be able to stock this many fish closer to the 33 gallon mark. Good luck!!
Use the softest sand you can find. And you definitely have room for all these fish! I set up an NPT the other day that is going really well with an inert sand cap over soil. I have kuhlis, cories, Endlers and female bettas - the kuhlis are amazing little fish!
A note: kuhlis and otos will both be happier in soft, acidic water, so if you have harder or alkaline water, they may not be ideal.
The sand I used is an aquarium specific one called silver sand - extremely small particle size, very soft, completely inert and very clean.
So yall are leaning more toward Bettas and Kuhlis with no Otos? Okedokey. What do you think would be a good number of each bomb? And where ddo I get that sand? Any compacting problems? Posted via Mobile Device
I'm not sure where you would get the sand in the US, unfortunately - I'd call around and see if any petshops have what you need. However, make sure you are talking to someone who actually knows what's what, not your average assistant who will probably give you gravel.
As for numbers, if you just go for the kuhlis and bettas (remember, you need soft water with a pH under 7!), then I'd have 8 of each, minimum. :) If you want to otos too, I'd have 6 bettas, 8 kuhlis and 6 otos.
I use the CaribSea Black Tahitian Moon Sand from Petsmart and I love it. It's fairly soft but I don't find it gets into my filter too much. With any sands you will need to churn it every now and then anyway so get whatever you like best. I usually churn a part of my 33 gallon sand after the water change on Saturdays and then move to a different section each week so if there are toxic gases, I'm not releasing them all at once.
There are so many options for plants but we need to know light specs for that, also will you be doing any fertilizers. Some of the more easy plants are Java Fern, Anubias, Anacharis, Water Sprite, Water Wisteria, Vallisneria, and Dwarf Sag.
