Answer 1

Maybe you just tossed the old filter and replaced it with a new filter...and you also changed 50% of the water..all the useful bacteria is gone...your tank has to go through the cycle process again...all this is useful bacteria bloom..when you want to change the filter (which is really not necessary frequently)..plan in advance...say 3-4 weeks prior to changing the filter..put the new filter in the tank..tht way it will start collecting useful bacteria...also don't do a water change and filter change at the same time...if you do a water change today...change the filter after a few days..this helps your water to retain at least some of the useful bacteria...also when you put the new filter...do not toss the old filter...let it stay in the tank for at least a couple of weeks.this helps you avoid the cycle...and less stress on your fish...currently I would suggest you test you water for ammonia and nitrites..and if the readings are more than 2ppm (which definitely would be)..do a 10-15% water change again...Read the following link..this shud help..

one has to be careful with the useful bacteria or else excessive ammonia and nitrite builds up and could kill the fish...

Answer 2

too many fish

plecos grow about 2 feet

i would say a 100 gallon tank but i dont know for sure
