I just love my Cories. They are really sweet. I have quite a few of these little guys, they love to come to the top of the tank to breath really quick gulps of air and sometimes they kind of stay around the top. I have a 200 L, a 100 L and four 40 L tanks, and I have Cories in all of them. They love the bubble bars that I keep in all of my tanks. They like to group around them and love to play in the bubbles. I recommend lots of these little guys, they are fun to watch.

I have 7 Sterbai "running" around my 530 liter tank. With their vacuum cleaner like behavior they seem to clean all the sand in my tank and wirl all the dirt into the pump, so they keep the bottom very clean at all times. They love strong currents and can spend quite some time just floating in it playing with the stream. They love sinking discs. But the most amazing thing about these small things, is that I can have them with my big Crenicichla Xingu I's without being harmed. Sometimes the Xingu's try to catch them, but the Sterbei is so fast, and because of the to spikey fins they have, they seem to have gained some respect. They live their own life on the bottom, sometimes sprinting for the surface to fill up with air. I recommend at least having 5 of them in a group, more is better. Always keep a little space between the surface and the light so that they can get air without bumping it.

I have 3 Sterbai in a 75 L community tank. I caught their latest spawn on video tape. The mating couple rubbed against each other as they swam around for several minutes. The female then attaches her mouth to the male collecting his sperm. She was very still for a moment while she laid 2 to 3 eggs held between her pelvic fins. She then deposited the eggs on the plants or glass. I'm not sure when the eggs were actually fertilized, but I assume it was while she was swimming so the flow of water would aid in the transfer from her mouth to the eggs. Before you know it, she was holding another few eggs and continued looking for a good spot to make a deposit. I filmed about 5 sets of 3 eggs. The water temp was 28°C (summertime) and I had been away from home a couple days previous, so the lights were off for that period. The entire tank was fed well before I left.

I have a few Cory's in my tank, including the Sterbai, Albino and the Peppered species. My first Cory was in fact the Sterbai and even though it was one of the first inhabitants of its kind in my tank, I didn't notice any timidness at all. In actual fact, it swam around the tank like it was in a world of it's own, not taking notice of the angelfish or Mr. Clown Loach! Anyhow, in my opinion the Sterbai Cory is the prettiest one of all the Corys - in terms of its pattern and colour. I think that's why it was the first Cory I picked, even though it was 3 times pricier than the rest of the Corys available at the LFS! I haven't really noticed it swimming to the surface, however, I always notice it vacuuming the substrate for scraps!

Sterbai corys are a great bottom feeder fish that are very entertaining to watch. They are relatively easy to care for and are pretty hardy. They will eat algae wafers and I feed mine a piece of cuccumber boiled for about 25 minutes. They should be kept in at least pairs. I have two and they hang out together and are good buddies. You will sometimes see them swim up to the surface and take a quick gulp of air and float down to the bottom. A very cute fish that looks like a mouse.

I just picked up a pair of Sterbai Cories from a family owned pet store. In the pet store they hardly moved at all. I had never seen them before so I was sold on how much better they looked than the other Cories I had seen. Within five minutes they became the most active fish in my tank. I have a 110 liter tall tank with a huge wet dry, and another 110 liter separate sump attached to the system. Lots of plants and caves and hiding places. Four German blue male rams, and 6 blue rainbows. If you're thinking about buying them, don't be afraid of the extra price. They are well worth it. My two cost me about $30 and I would have paid twice that.

Sterba's corys are a schooling fish, the more you keep the more you'll see of them. I started off with four and when they had settled in they swam all around the tank and weren't shy at all. I lost one of them and I noticed straight away that they didn't come out as much. The three of them would hide up the back of the day all day. If you have less than three you may only see them at night. They are an interesting and cute fish to watch and do a good job at cleaning up after the other fish. They make a good community fish and won't scare other delicate fish like discus and altum angelfish.

I have 6 of these brilliant little fish in my 180 litre tank. They do great! Don't let the heavy price tag put you off. Mine cost me £30 (US$60), and I got what I payed for! They are active, fun to watch and they have brilliantly coloured yellow fins. 110% satisfied!

Update: Soon after their purchase, the corys started to become less active, and die off. They where kept over a gravel substrate that looked smooth - but it wore down their barbels. 3 dead corys later - I switched to sand substrate. The 3 remaining corys are doing great! They seem much happier now they have sand - especially their black sand. These are really great fish - even if they produce a little more work!
