no i didnt cycle the tank,,becouse i never intended to keep fish, but someone died and the fish were getn rid of 1 way or another,so i said id have them,the tank i got with the fish in had no filter. and was about a 10litre tank with no light or hood,so i went bought a 60l tank,1 fluval u2 filter, i knew nothing about fish.there is 2 common plecos 3platys 6 neons 5 zebras 3 corys , anyway wen i got the new tank there was more fish then but i lost a fish everyday 4 a week,i didnt know what to do,and thought rehoming them was the best thing,to put them in abigger tank with a filter and sum plants and a light.since i put them in this tank 3 weeks ago ive only lost 1 fish,which im sure got stuck under pump. maybe not? but what am i meant to do with them now,as ive only 1 tank now.the fish are fine ,i will buy a water testing kit for water ,but oter than that i dont know what to do. if i hadnt of took the fish they would have been dead by now,
Hang on, let me get this straight, your post was a bit confusing!
You got the fish in a 10l tank where one fish was dying a week. You then put them in a 60l with plants and a light, right? I'm getting lost with all these mentions of tanks!
By 'rehoming' we meant find them a new home - back at the fish shop, with someone else with a bigger tank, etc, not 'rehoming' them into a 60l because that's still not big enough for the plecs.
THIS is the size you can expect your two common plecos to get to, unfortunately. That's why I didn't understand what you meant about 'putting them back in' later.
HERE is some info on fish-in cycling, which is what you're doing now. It's not easy but it is certainly doable - it will be more difficult for you because of the large number of fish you have, particularly as those two plecs will produce a massive amount of waste which will worsen the water quality.
Basically, you'll need a testing kit (for ammonia and nitrite at least), and a lot of water changes!
