What fish and how many

[Harryfreshwater97]

Hello, I’m new to the hobby, I’ve had my 180 litre fresh water tank set up for 4-5 weeks now and all my levels for ammonia/nitrites are 0, I’ve just put 10 otocinclus In and they are doing perfectly fine, they seem super happy, i sort of know what other fish I want In there but I didn’t know how many fish I can put in, I wanted 2 electric blue rams, 2 angelfish and then some tetra, but was unsure how many tetra I could put in to finish the tank. Any replies and help would be amazing, thanks.

I can’t advise on fish, too new and just don’t know, but what is your water like..? Hardness, Ph etc.? Do all of those fish need the same type of water parameters..?
http://www.aqadvisor.com is a good place to start with planning numbers, once you’ve got that sorted come back and ask about things like compatibility which the websites don’t usually give.

Otos need planted mature aquariums as they feed off algae on plants, rocks, sponge bobs and tank sides. I hope five or six weeks will be old enough for them.
Post your water details: hardness, ph, temp etc then check them with seriouslyfish.com to see if you’re fancied fish are suitable.
Then come back on here to check as not all fish are suited to living with each other and seriously fish can’t cover everything.

Best of luck

Hardness has been mentioned - look on your water company's website for hardness. You need a number and the unit of measurement (there are several they could use). If you can't find it, tell us the name of the company and we'll see what we can find.
