help figuring what thei fish is

lol it's hard from the discription if not immpossible sorry i'm no help :[

 

without a photo it will be impossible to tell you, at most all we can do is give you a guess according to your details provided.

At best, my guess would be a Raphael Catfish.
The u-shape is the part that got me [scratch] ....all the raphaels I've seen are straight stripes? (but specimens can be unique like people)

 

i agree with the others...need a good photo to help with id..

 

Scientific Name: Platydoras Costatus
Common Names: Raphael Catfish, Talking Catfish
Size: 6 - 9 inches
pH: 6.5 – 7.6
Temperature: 75F - 80F
Temperament: The Raphael gets along with most fish, do not put him with anything that can fit in it’s mouth.
Lifespan: Average of 10 years though some have been known for living more than 15 years
Breeding/Mating/Reproduction: Difficult to breed in the home aquarium
Tank Size: More than 30 gallons, preferably 55 gallons
Catfish Disease: They have been known for being delicate towards ICH treatments, so dose carefully
Diet/Fish Food: Will accept most food such as sinking catfish pellets, blood worms, flakes, etc.
Tank Region: They are bottom dwelling and need a few caves and PVC pipes to keep them entertained
Gender: Some say the males are not as fat as the females. Females have very round bellies since they are carrying eggs. Another way to tell them apart
(for the striped raphael’s) is the males tend to be more darker in color. The females are more of a cream color between the stripes, while the males have a yellowish tan color.

I wouldn't chance it with corys unless there's lots of places for the corys to hide out, which one of your tanks were you planning on putting it in?
