Guess what my hubby brought today? 3 four-lined catfish and 3 common plecos. They will be stationed in the 40 gal tall with the only 2 inhabitants (1 Angel and 1 Emperor tetra). We will keep them until they outgrow the tank or we can afford that dream tank of his.

Does anyone have any experience with these fish species? I can't find anything in the profiles? And a google search comes up with 4-lined Pimodella or Pimelodus blochii. How fast/slow do these fish grow?

UH OH.

4-lined pim will grow really fast. That emperor tetra will disappear within a couple months down one of their gullets. I've never kept one, but that entire family (Pimelodidae) includes fast-growing fisheaters. These can probably reach adult size within a year if really well fed, but it could take longer in a tank as small as a 40 gallon tall.

A trio of 4-lined pims will be okay in a 100+ gallon. Common plecs have the capacity to get a lot larger, but I've also only seen very few of them get to such sizes, they tend to get stunted more easily I think.

Thanks Shinigami! Can you tell me how big to expect them to get? All of the sites I've been to on the 4 lined pim never give a flat out size and they all vary greatly. Will they stay slim or become chunky?

I told my hubby the tetra will have to be moved.

He told me, "No, the catfish want to know there food before they eat it.

Since I haven't seen any larger, I'd say the 9-12" mark is probably about as big as they'll get. That's not to say that they don't get larger than that, I just haven't seen any that are bigger. When they're bigger they will be quite a bit chunkier.

Not knowing how big the pims are now, I would not dilly-dally on moving that tetra. Catfishes, and pims especially, have surprisingly large mouths.

I just checked on them. There stomachs are distended from their first feeding already. The tetra is so far safely sleeping topside. The pims finished the single sinking wafer before the plecs knew it was in the tank. I just had to drop a second one in so the plecs will have a chance at it.

You may have to feed other things for the plecs... I used to keep my royal plec with a sizeable catfish, but when the catfish started swallowing algae wafers whole that's when he had to go. Plecos will eat veggies with gusto, though, and the pims will leave that alone.

Do you think the plecs will fancy mango or peas?

I don't tend to use peas, but other aquarists have said that peas are good. I think you have to peel them.

I'd watch out with anything really juicy like mangoes, as the juice could affect the water quality, although every now and then is okay. I'd also be careful with mangoes specifically because their skins contain urushiol, which is what poison ivy has that causes the reaction. I don't know the effect of that on fish, but there's no reason to risk anything when there are many other choices.

Cucumber, zuchinni, and lettuce have good track records as pleco foods.

I've fed my 55gal thawed squeezed peas without problems, so I'll give it a go with the plecs. I also gave the 55gal a sliver of peeled mango day before yesterday, and the barbs shredded it. I don't plan on sharing my mangos with the fish too often. I have to share with the kids enough as it is.

Tonight, I just fed with flake food. But I did drop a few (5)pieces of thawed mixed veggies (a kernel of corn, 2 peas, and 2 diced squares of carrot) in the tank to see if the plecs will eat. So far, everyone but the Angel has ignored the veggies. (he decided he didn't like it and left it alone too.) I'll check in the morning to see if it's all still there.

How long can I leave uneaten veggies in the tank? I dropped a few in last night, and most of them haven't been eaten. Also does it matter what kind of lettuce? Can I use spinach, kale, or collard? What about a slice of tomato flesh minus the seeds?

Ive had good luck with blanched spinach, cucumber and zuchinni, and shelled peas.

I've never tried carrots or corn... not to sure about the corn as peas need to be shelled, corn would need to be also as its got a harder shell than peas...

I put in a small amount at nite, and take out whatever isnt eaten the next am. Not sure about how long you can actually leave it.

Carrots work, but I haven't heard of corn. I have heard of tomatoes, but I wouldn't use them often because of their juice and acidity.

You can use any lettuce. I usually use iceberg or romaine. I have also used cabbage, and napa. I might've used kale once. I tend not to use lettuce as much as zuchinni and cucumber, however, because the latter hold together better instead of breaking apart.

I avoid spinach as it contains oxalates/oxalic acid, which can be bad for people at high concentrations/bad for people not tolerant of oxalates. Considering a fish is several times smaller than people, anything remotely dangerous to people could be more dangerous to fish. That said, I have never heard of a fish dying because of a spinach diet, which could mean I'm just super paranoid.

I usually leave veggies until they're eaten, which is within two days depending on how much I put in. Veggies start to disintegrate after that, and you should of course take it out when that starts to happen.

Thanks for all the answers to my crazy questions, guys, especially Shinigami. Hopefully just one more. Will yellow squash work instead of zuchinni? We tend to eat more yellow than green when it comes to squashes.

Okay, maybe one, one more question... How do you entice the plecs to eat? I noticed they will only stay on the glass or anything they can blend in with.. i.e. the dark brown driftwood, the black heater, the black thermometer strip. Since the food is light colored, I can't seem to get them to go near it.

If you feed them right before the lights go out, this should help. They may be shy in bright light during the day due to their natural inclination toward nocturnal activity.

You could also try attaching the food to a dark surface, like your driftwood. This should make them feel more comfortable than the exposed open-gravel area of your tank. (In time this shouldn't matter as they become used to the environment, but I suppose it depends on the personality of your fish.)

I looked it up and a number of people report success using yellow squash, though I have never used it. Should be fine.

As they're common plecs, there really shouldn't be too much trouble getting them to eat once they realize what's food; all the foods I feed are similarly light colored. These guys have probably eaten algae wafers and shrimp pellets their entire life, but probably have never seen real veggies before. They'll learn soon enough, it usually doesn't take too long.

I usually don't worry about them eating if they at least eat it at night. Some of my plecs eat during the day, while some only come out at night.

Found a plec dead in the front of the tank. I don't see any signs of anything wrong, but then I haven't seen any evidence of them eating anything yet either.

I'm sorry to hear that. =/

Do you happen to have a small rock or piece of driftwood you can place in a bright windowsill for a day to grow some algae? Placing this in the aquarium may give them some natural food as well as a potential shelter, encouraging them to eat.

Hopefully the rest will make it out OK.

It would take a LOT longer for a plec to starve to death, from my experience when I was a beginner (when I didn't know plecs needed to eat something other than algae in the tank). Their bellies would be sunken and they usually get pale patches if they starve in this manner.

You just confirmed that it starved. It had pale patches on the underbelly. I noticed that when I tossed him out.

On a brighter note, I did see the other two had gnawed on the yellow squash this morning before I pulled it out. I will get them something green to eat later today. I have some kale frozen in the garden, (I was too lazy to clip it before the frost.) maybe I can give them that? I also have a vase that's been sitting in the windowsill. Can I scrape the algae out of that? I don't think it will be the solid sheet kind. Oh, will they eat the algae that grows on the underside of the hood? That usually comes off in a big clump. (kinda gross looking to me though.)
