This fish has two qualities which make this a great community fish: active and peaceful. Also, a hardy species which will not make many demands on the water, but slightly soft, acid water is preferred. Being a mid-swimming shoaler, it requires open spaces at the front of the aquarium, and thick plantation at the rear and sides so that it may hide. If given plentiful vegetable matter in it's diet, M. sanctaefilomenae should refrain from nibbling the aquarium decor. It's omnivorous and has a good appetite.

Great schooling fish. I've got nine of them on my 110 L planted tank. They say that these guys tend to nip fins, but keeping them in a large group seems to temper them. Females are larger and rounded, while males are smaller and more slender. This is a great community fish!

These are good fish, wonderful in their own right. They do tend to be nippy (as are a lot of Tetras) especially when placed in tanks with slow moving and/or long finned fish. When kept in schools of 5 or more in at least a 200 L tank they seem to get along well, but any number less tends to cause a bit of skirmishing where one turns bully. Also, I can't emphasize this enough, as with pretty much all Tetras, they are a schooling or semi-schooling fish. A single fish will hide constantly and as said before, any number less than 5 seems to cause bullying. Another problem with these fish isn't even the fish's fault, but rather ignorant or money hungry pet stores who often cite them as a great community tank fish with smaller varieties such as neons and guppies. Sure, when small they can get along with them, however, under good conditions and regular feeding they will end up to a size where they'll view their smaller tankmates fins and all as dinner. My first experience with these fish was such a scenario. I was a beginner and found out later the dire mistake I made listening to Pet Store clerks. Keep them with larger, active fish such as barbs, gouramis, paradise fish and such and you should have no problems. Care wise, they are pretty hardy fish. Mine were as tough as nails, having survived many a trial as I groped my way through the early years of fish care, including a summer in a 1900 liter outdoor pond, which they loved so much I had to actually drain them to catch them...and their six 3 cm long babies before winter (unfortunately, I didn't view their breeding as everything occurred without my knowledge.) They do love plants, so keep only tough-leaved plants in with them and give a few bit of duckweed every so often along with live food such as mosquito larvae, brine shrimp, or tubifex worms. Believe me, all fish show their best colors when given natural foods.

I love tetras. There was a time when I didn't know anything about fishes. So one day I went to the shop and bought red serpae tetras, red eyed tetras and neon tetras. I loved the neon tetras the most because they cost a lot. I mixed them and watched them swimming happily in my new tank. The next morning I was suprised to see one of my neon tetra died with severe wounds. The same thing happened and happened until there was only one left. I must catch the culprit I thought. That night I switched off the lights and spied on the tank. It was the red eyed tetras all along. They shoaled and started to chase my neon tetra and nipped it. Then I asked the shopkeeper and he told me red eyed tetras should not be kept with smaller or long tailed fish.

Perfect community fish. I had a one-eyed specimen, which I bought because I felt sorry for it in the shop and it out survived nearly everything in my tank. It was great to watch as it has a somewhat piranha look to it and has a great set of tiny teeth. Highly recommended.

I have exactly two. I didn't get more because I have a small tank. The two I have look all beat up because they are constantly nipping at each other. On the bright side, they're otherwise healthy. I've kept them for about 2 years now.
