I added one to get spirogyra under control. It decided stargrass is more delectable and removed every new bud from a large bush overnight. It also tore a few chunks out of some val nana in what seemed to be a newcomer's dominance display. It was moved to the backyard pond shorty after. Pretty fish with funny behavior.
The colors in the American Flag Fish are beautiful. I purchased 4 of them to go into my 125 gallon aquarium just yesterday. They were acclimated and placed in a 20 gallon aquarium that houses cherry red shrimp (this allows me to tell if a fish I am buying will eat them) and by morning their were about 4 left. The AFF didn't even bother to eat breakfast. Hmmm... Wonder why.
Anyhow just as a warning these guys MAY eat your shrimp and will nip fins on larger fish.
I added 5 to my 55G planted to eat some hair algae. Within 24 hours, they wreaked havoc in my tank going after anything that was smaller than them. I lost 4 fish and they did not touch the hair algae. I threw them in my 75G planted that houses large Danios, and some Dwarf puffers. All is fine now. BTW the females were just as aggresive as the males.
I have found flagfish to be somewhat flashy in their aggression but more bark than bite. However, they do like to taste-test shrimp, persistently gnaw on the ends of grass-like plants (not sure if they do damage here) and rip moss into unidentifiable pieces. On the bright side, they have a lot of personality and are always grazing.
I made a mistake and believed the retailer when I bought four of these lawn mowers. The good thing is it ate all of my hair algae. The bad thing is when it ran out of algae it turned on my innocent plants. It loves UG and star grass. I have been able to get 2 of the four out of the tank. I'll try to get the other 2 in the morning. Pretty fish.....that's about it. Oh yeah....they are also bullies to my corydoras.
Colourful and great for algae control, but should be kept well fed after the algae subsides or they might turn on softer plants and mosses. They love spirulina wafers. They're a bit boisterous and as such are better tankmates for the tougher barbs (rosy, tiger, etc.) and tetras.
The absolute best fish for cleaning up algae! I personal observed them eating every form of algae that grows in a home aquarium. Remember if you have a community tank then only keep females since males are aggressive and territorial! If you keep duck weed they will stay away from your plants and pick at the roots of the duckweed but since duck weed multiplies so quickly it will always be there for them to graze on. I keep 3 females in my 300 gallon and since they have arrived my tank has been totally clean of BBA!
Have 2 of these ,1 small and 1 larger .The smaller one loves BBA, bigger one only eats it when starving.Had F flag fish 5 years ago learned the smaller the fish the more BBA it will eat.have mine with adult ghost shrimp small ones i can see them eating, neons,sae,and angelfish all get along no nipping i have noticed.Beautiful fish
I have 6 of these in a 15 gallon breeder tank and 6 in my main 40b and I see none of the aggressive behavior others are saying. I'm not sure what I'm doing that is different from others but if I had the problem others seem to I sure would know it with rasboras, cherry barbs, and neons in there. On one site a breeder says that keeping these fish well fed is the key to curbing aggressive behavior. I have tons of floating plants and they love hiding in the roots of water lettuce. They are truly fantastic fish to observe!
I've read that these fish do best in heavily planted tanks in groups (one person had success with breeding them in a 20 gallon with 1 male to 5 females). Surprisingly, they do not bother plants as much if the tank is densely planted - planted tanks which are not particularly densely planted are vulnerable to being ripped to shreds. This is what I've read about them.
Son came home with 5 of these in a bucket. I was going to tell him to take them back to the swamp until I netted one out and looked at it. I looked them up in my Axelrod's Atlas and then transfered them into a 60 Oceanic I had set up at the time with semi-aggressive fish. Schools of very large Rosy Barbs, Green and regular Tiger Barbs, a Giant Pearl Gourami and some talking cats. Needless to say- no real plants. They were great, very personable. :D
I have three of these in an 80 gallon with other North American natives. I haven't seen any aggression (in this tank they are among the shyer inhabitants) or plant munching but they do graze on algae all day. I also have duckweed in the tank so maybe that is keeping them from eating other plants.
