plecostomus fish good or bad idea

I just bought myself a plecostomus fish, the one that cleans the tank, for my 5 gallon tank. I just read however they can get very big. Is that true, or do they on get as big as the tank space? Worried new owner.

Probably ought to take him back. Is he a common pleco?
Oto's are great algae eaters. They like the brown algae that is common in newer tanks. Plus, they are cute and stay small. But you have to keep up on your water changes, they can be sensitive to water quality. Just another reason to do what we know we need to. :)

Ok but do otos eat the junk from the rocks? Plus I have brown algea as well so that is good. Also are there other species that clean more than the algea, and won't get that big.

Well, if by 'crap on the rocks' you mean another type of algae, I think they may eat some green algae if they can't find enough of the brown, but some other types of fish like the green better than they do, I believe. If you mean fish poop, nothing will eat that. The only way to remove it is by vacuuming your gravel, which you can do easily with every water change, whice needs to be done at least once a week.

yes... common plecs can get HUGE. best to take him back. there are a few dwarf pl*c varieties that are cute and make for decent algae eaters... i recently got a young rubberlip, and he/she had my glass clean overnight. however, these guys are probably too big for your 5g as well.

amano shrimp (cardinia japonica) are a good bet... they will eat just about anything. and their wacky antics are great when you catch them out and about.

otos are great too... stay fairly small, and some of the cutest fish in the world imo.

and for the sake of your gups... avoid chinese algae eaters and golden algae eaters like the plague. these are the guys that are usually just labelled "algae eaters" at most lfs. it's a bit of a misnomer; they actually prefer giving your fish vicious skin-breaking hickies and sucking off their slime coat to eating algae... a condition that only gets worse as they mature and get huge.

however, you should not be relying on fish to keep algae at bay. there are likely more sinister workings afoot that are causing your algae bloom, whether it be poor light spectrum (is your light source fluorescent? color temp. at least 5000 Kelvin?), excess nutrients in the water (is there anything weird added to your area's tap water?), too much nitrate (perhaps your fish need more frequent water changes?), need for co2 injection, etc.

that being said... i think you're probably at or extremely close to your limit in a 5 gallon tank with six guppies. any more fish added could arguably constitute overcrowding. so perhaps consider a larger setup, or getting more anal about tank maintenance, scrubdowns, etc.

Shrimp would be good IMO. Not overfeeding is important to water quality, which is everything to your fish's health. Regular vacuuming is essential. Shrimp will help with cleanup in between vacuumings.

Ghost shrimp are ridiculously cheap and they stay small. I have them in my guppy tank, no problem. They are also in my betta tank as well. Larger fish, like goldfish, for instance, will regard them as a yummy meal.
