I am currently getting my old ten gallon tank ready for a new project and right now I could use some ideas. I've have the tank for about at least 19 years, at least half way towards 20, and when I've upgraded to a 20 gallon tank, it's been collecting dust. Right now everything is getting cleaned, the tank of dry hard water residue and algae, rinsing out the gravel and wiping down the equipment, although I would have to replace the bulb since I've had it for years and it wasn't until recently when I found out you need to replace them after a couple of years. I have a Whisper internal Power Filter, one of those deals that has suctions cups you have to stick on the inside of the wall.
Right now I'm wondering what would be a good project to use it for, either for fish, or some other animals, and wouldn't mind some suggestions. If it is going to be fish, then I would like some ideas on what would be a good combination to add to it, one fish I would like to get on algae control is a bristlenose pleco, anything else is up for grabs, if it's a freshwater tank. Another fish I would like to get is a gourami, like a Blue, Kissing or Pearl. I wouldn't mind turning it into either goldfish tank or turning it into something that revolves around White Clouds.
I am also thinking about trying for a brackish fish tank, like puffers or mollies, but I would need help on knowing which fish would be perfect for both slightly salted water and small tank and which would be a bad idea. Basically advice for a beginner since I'm used to doing freshwater.
Another idea is going for something like hermit crabs or something else that has nothing to do with fish, but like I said before, open to ideas.
And on a final note, what would be a good plant to add to it, especially size wise, especially if brackish water would be involved, and what won't be eaten by a pleco once added.
Thanks in advance for those who read this.
