well i gave my little sister a 2 gallon hex tank for her 13th birthday in may and she has gotten bored with the RCS and the 2 male endlers i put in there for her. She HATES betas with a burning passion, i don't know why but she dose. the tank is currently running as a planted tank (wel sorta, one aponogin in the center with a ring of lava rocks around it to corm a little "island" and then a bunch of java moss that has grown out of control.) The sub straight is mint green gravel with some black mixed in (looks like mint chocolate chip ice cream but thats what she wanted.) with an under gravel filter. What else could i do with a tank that small? she docent want shrimp, betas, those dwarf frogs, or anything else that i can think of. any ideas?
