Hello,
i am new too website. Fishkeeping 3 years.

Just purchased a 20 gal long aquarium 30 x 12.5 x 12.5 inch.

I am cycling with 4 zebra danios. 4 days now. I bought 2 syn0dontis petricola cats. They are doing well. I used treated substrate and bacteria from other tank.

When i stock in a week or so, any advice on cory's and my synodontis

appreciated

thank you for your time

Hello and welcome to TFK. I strongly suggest in a 20 long that you do not add any other bottom feeder with two petricola cats. The cats are going to grow to 3.5", sometimes even topping out at 4". Corydoras ideally should be kept in groups of six or more individuals. The corydoras scavenge all day, the cats will generally come out at night. You can easily starve out the cats with the corys. If you had a 55 or larger tank you could possibly consider them. I think eventually you may find this 20 long is too small for these catfish. I have a synodontis nigrita in a 90 gallon tank. I couldn't even imagine him living in a 20 gallon.

Thank you for the reponse

I will consider your suggestion.

Another thought. If i don't add corys what about more synodontis?

I have heard mixed advice on corys and synodontis.

If no corys. How many synodontis?

And what about a smaller pleco?

I am gonna stock black neon tetras and cardinal tetras after the cats

at least another 2 weeks or more

thank you for your time

If you are asking me, refer back to my post. I suggest strongly that the two cats you have are enough bottom feeders in a 20 gallon tank. Any kind..plecos included. Most plecostomus get huge unless you luck up on a small type from a breeder/seller and those are generally quite costly. Again, they need to be kept in groups, and a 20 long is just not big enough for all the big fish you want. Eventually in this hobby you will find out that less is more, and overstocking always leads to issues you do not want.
