I think it is axolotl.... google search, you can match it =D Here they are illegal, you lucky duck lol. I love them!! D:
Anyways before taking the dividers out I suggest strongl,y getting tons of plants... Java fern, floating plants, moss, etc. TONS. I mean TONS. Like....stuff the tank tons. Trust me xD Same with soft fake plants too
Although... Not sure on the axolotls sizes, but if they are about the same size, and adults (6 inches, btw....) they are less likely to attack each other but CAN attack fish that are smaller than them... The rule of mouth
Fits in their mouth, they eat it. Seems like it fits in their mouth, they'll try! So best be warned for the future (here is an info page http://www.axolotl.org/requirements.htm#other
) I think you have axolotls because of the feathery gills xD Just be warned, the tank needs to be big for axolotls to get along nicely... Plus they get 6 inches
So, just a future heads up :3
Anyways I have females ranging from one inch to 2 inches right now. The one inch ones were severely stunted, but if you have ones who are decently sized, good food and clean water is a must for good health and they may get bigger! And another caution... Axolotl are cold water fish... They like it below 75,although they are fairly hardy and forgiving (much like bettas, hey?
