I'm not really sure, but I recently saw some Blue-Rams. Those are pretty impressive looking.welcome! There's alot of options for a 25g tank so first tell us what you like and we'll help it work or you!-Brandon
darn (that they're tough to keep). They are the most amazing looking freshwater I've seen.welcome to the site! Whisper Airpumps are pretty quiet.
rams are considered difficult to keep because they need low pH and an established tank, though just because they are difficult to keep they are not difficult to breed-i see egg-filled females in dealer tanks all the time. i plan on trying them out in a 55 gallon soon.
