Do some shopping and ask questions. I have found really nice small aquarium shops in my city. Many selling healthier and more beautiful fish than their conglomerate cousins. Their are many types of cleaning fish i am a pleco fan and would recommend you take a look at the many varities before you buy. Some are harder to take care of than others though. Find the right fit for your tank scheme, take your time you will be fine. Good luck.jayfl234 said:i have been wanting a pleco for my 29 gallon tank. Would my tank be big enough for one or maybe something similar?
