Who Gives A Fish Forums

Thanks for the tips, everyone. Gonna try the gravel vac and reduce the light time. I've been doing weekly changes but might bump it to twice a week if the algae keeps up.

My betta tank's getting kinda sketchy, algae on the glass and substrate's dirty. What's the best way to clean it without messing with my fish too much? Got a 5-gallon with a sponge filter, no tankmates.

Ever heard of the Candiru? Tiny parasitic catfish that supposedly swims up your urethra. Dunno if it's true, but the stories alone make me wanna wear armor in the Amazon.

What about the Stonefish? Heard they're venomous as hell and look like rocks. Not sure if anyone actually keeps 'em, but dang, that's a risky pet.
