16 here -
I had a 10 gallon that i setup as a temporary hold (sister bought 2 dempseys for a 5 gallon - needed to be seperated), but that is down now, and in it's place is a convient 29 gallon with cichids (these are all american cichlids, my dad used to have africans, and i like the americans better just because i think they have more "personality").
I have a 5 gallon hex in my little sisters room (6 years) that i maintain for her with 2 rosy barbs thats pretty nicely planted. No PC lights needed either, just the whimpy incadescent one that came with it did the job due to the sunlight her room gets - No algae luckily though
5 gallon eclipse downstairs that only has 3 snails in it now - soon to probably be a dwarf puffer tank or maybe a betta.
28 (wierd metric sized tank - ViaAqua - got it for almost free
) With a large oscar in it and 2 african claw frogs and a small pleco of some sort (doesn't seem to be growing near the rate of normal pleco's, it's striped white - so who knows). The tank is getting smaller as we speak (ohh, wait, maybe thats the huge fish just growing still :nervous: )...uh oh, i sense a 55 kit from wallmart to replace that tank.
30 gallon going up soon in place of the 10 out of my room (dads taking 10 into office). Just gotta finish painting which is actually my plans for today, take the carpet up, and pray for nice hardwood beneith - otherwise i'm gonna be shopping for a bunch of area rugs. This one is going to start as FOWLR and eventually be converted into a reef with gradual investments :thinking: .
All I have to say is I'm lucky I only have to pay for 1/2 my car insurance (get parents gas card, and a car to use), my gaurding recertification, and my girlfriend. Otherwise, my wallet would not be able to support these tanks.
